                         - IsKeyPressed(MY_NATIVE_KEY_XXX)              -> use IsKeyPressed(ImGuiKey_XXX)
                         - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX))      -> use IsKeyPressed(ImGuiKey_XXX)
-                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent()
+                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes).
                         - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiKey_ModXXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiKey_ModXXX values.*
                      - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
                      - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.

+// About imgui_impl_opengl3_loader.h:
+//
+// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,
+// which proved to be endless problems for users.
+// Our loader is custom-generated, based on gl3w but automatically filtered to only include
+// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
+//
+// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.
+// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
+//
+// Regenerate with:
+//   python gl3w_gen.py --output ../imgui/backends/imgui_impl_opengl3_loader.h --ref ../imgui/backends/imgui_impl_opengl3.cpp ./extra_symbols.txt

+

+  per channel data, the significant bits value can be used to indicate the original encoded data has another
+  sample depth, such as 10 or 12.
+
+  Encoders using this value, when storing the pixel data, should use the most significant bits
+  of the data to store the original bits, and use a good sample depth scaling method such as
+  "left bit replication" to fill in the least significant bits, rather than fill zeroes.
+
+  Decoders using this value, if able to work with data that's e.g. 10-bit or 12-bit, should right

+  sbit and work e.g. with the 8-bit or 16-bit data from the PNG directly, since thanks
+  to the encoder contract, the values encoded in PNG are in valid range for the PNG bit depth.
+
+  For grayscale images, sbit_g and sbit_b are not used, and for images that don't use color
+  type RGBA or grayscale+alpha, sbit_a is not used (it's not used even for palette images with
+  translucent palette values, or images with color key). The values that are used must be
+  greater than zero and smaller than or equal to the PNG bit depth.
+
+  The color type from the header in the PNG image defines these used and unused fields: if
+  decoding with a color mode conversion, such as always decoding to RGBA, this metadata still
+  only uses the color type of the original PNG, and may e.g. lack the alpha channel info
+  if the PNG was RGB. When encoding with auto_convert (as well as without), also always the
+  color model defined in info_png.color determines this.
+
+  NOTE: enabling sbit can hurt compression, because the encoder can then not always use
+  auto_convert to choose a more optimal color mode for the data, because the PNG format has
+  strict requirements for the allowed sbit values in combination with color modes.
+  For example, setting these fields to 10-bit will force the encoder to keep using a 16-bit per channel

+1. about
+--------
+
+PNG is a file format to store raster images losslessly with good compression,
+supporting different color types and alpha channel.
+
+LodePNG is a PNG codec according to the Portable Network Graphics (PNG)
+Specification (Second Edition) - W3C Recommendation 10 November 2003.
+
+The specifications used are:
+
+*) Portable Network Graphics (PNG) Specification (Second Edition):
+     http://www.w3.org/TR/2003/REC-PNG-20031110
+*) RFC 1950 ZLIB Compressed Data Format version 3.3:
+     http://www.gzip.org/zlib/rfc-zlib.html
+*) RFC 1951 DEFLATE Compressed Data Format Specification ver 1.3:
+     http://www.gzip.org/zlib/rfc-deflate.html
+
+The most recent version of LodePNG can currently be found at
+http://lodev.org/lodepng/
+
+LodePNG works both in C (ISO C90) and C++, with a C++ wrapper that adds
+extra functionality.
+
+LodePNG exists out of two files:
+-lodepng.h: the header file for both C and C++
+-lodepng.c(pp): give it the name lodepng.c or lodepng.cpp (or .cc) depending on your usage
+
+If you want to start using LodePNG right away without reading this doc, get the
+examples from the LodePNG website to see how to use it in code, or check the
+smaller examples in chapter 13 here.
+
+LodePNG is simple but only supports the basic requirements. To achieve
+simplicity, the following design choices were made: There are no dependencies
+on any external library. There are functions to decode and encode a PNG with
+a single function call, and extended versions of these functions taking a
+LodePNGState struct allowing to specify or get more information. By default
+the colors of the raw image are always RGB or RGBA, no matter what color type
+the PNG file uses. To read and write files, there are simple functions to
+convert the files to/from buffers in memory.
+
+This all makes LodePNG suitable for loading textures in games, demos and small
+programs, ... It's less suitable for full fledged image editors, loading PNGs
+over network (it requires all the image data to be available before decoding can
+begin), life-critical systems, ...
+
+1.1. supported features
+-----------------------
+
+The following features are supported by the decoder:
+
+*) decoding of PNGs with any color type, bit depth and interlace mode, to a 24- or 32-bit color raw image,
+   or the same color type as the PNG
+*) encoding of PNGs, from any raw image to 24- or 32-bit color, or the same color type as the raw image
+*) Adam7 interlace and deinterlace for any color type
+*) loading the image from harddisk or decoding it from a buffer from other sources than harddisk
+*) support for alpha channels, including RGBA color model, translucent palettes and color keying
+*) zlib decompression (inflate)
+*) zlib compression (deflate)
+*) CRC32 and ADLER32 checksums
+*) colorimetric color profile conversions: currently experimentally available in lodepng_util.cpp only,
+   plus alternatively ability to pass on chroma/gamma/ICC profile information to other color management system.
+*) handling of unknown chunks, allowing making a PNG editor that stores custom and unknown chunks.
+*) the following chunks are supported by both encoder and decoder:
+    IHDR: header information
+    PLTE: color palette
+    IDAT: pixel data
+    IEND: the final chunk
+    tRNS: transparency for palettized images
+    tEXt: textual information
+    zTXt: compressed textual information
+    iTXt: international textual information
+    bKGD: suggested background color
+    pHYs: physical dimensions
+    tIME: modification time
+    cHRM: RGB chromaticities
+    gAMA: RGB gamma correction
+    iCCP: ICC color profile
+    sRGB: rendering intent
+    sBIT: significant bits
+
+1.2. features not supported
+---------------------------
+
+The following features are not (yet) supported:
+
+*) some features needed to make a conformant PNG-Editor might be still missing.
+*) partial loading/stream processing. All data must be available and is processed in one call.
+*) The hIST and sPLT public chunks are not (yet) supported but treated as unknown chunks
+
+
+2. C and C++ version
+--------------------
+
+The C version uses buffers allocated with alloc that you need to free()
+yourself. You need to use init and cleanup functions for each struct whenever
+using a struct from the C version to avoid exploits and memory leaks.
+
+The C++ version has extra functions with std::vectors in the interface and the
+lodepng::State class which is a LodePNGState with constructor and destructor.
+
+These files work without modification for both C and C++ compilers because all
+the additional C++ code is in "#ifdef __cplusplus" blocks that make C-compilers
+ignore it, and the C code is made to compile both with strict ISO C90 and C++.
+
+To use the C++ version, you need to rename the source file to lodepng.cpp
+(instead of lodepng.c), and compile it with a C++ compiler.
+
+To use the C version, you need to rename the source file to lodepng.c (instead
+of lodepng.cpp), and compile it with a C compiler.
+
+
+3. Security
+-----------
+
+Even if carefully designed, it's always possible that LodePNG contains possible
+exploits. If you discover one, please let me know, and it will be fixed.
+
+When using LodePNG, care has to be taken with the C version of LodePNG, as well
+as the C-style structs when working with C++. The following conventions are used
+for all C-style structs:
+
+-if a struct has a corresponding init function, always call the init function when making a new one
+-if a struct has a corresponding cleanup function, call it before the struct disappears to avoid memory leaks
+-if a struct has a corresponding copy function, use the copy function instead of "=".
+ The destination must also be inited already.
+
+
+4. Decoding
+-----------
+
+Decoding converts a PNG compressed image to a raw pixel buffer.
+
+Most documentation on using the decoder is at its declarations in the header
+above. For C, simple decoding can be done with functions such as
+lodepng_decode32, and more advanced decoding can be done with the struct
+LodePNGState and lodepng_decode. For C++, all decoding can be done with the
+various lodepng::decode functions, and lodepng::State can be used for advanced
+features.
+
+When using the LodePNGState, it uses the following fields for decoding:
+*) LodePNGInfo info_png: it stores extra information about the PNG (the input) in here
+*) LodePNGColorMode info_raw: here you can say what color mode of the raw image (the output) you want to get
+*) LodePNGDecoderSettings decoder: you can specify a few extra settings for the decoder to use
+
+LodePNGInfo info_png
+--------------------
+
+After decoding, this contains extra information of the PNG image, except the actual
+pixels, width and height because these are already gotten directly from the decoder
+functions.
+
+It contains for example the original color type of the PNG image, text comments,
+suggested background color, etc... More details about the LodePNGInfo struct are
+at its declaration documentation.
+
+LodePNGColorMode info_raw
+-------------------------
+
+When decoding, here you can specify which color type you want
+the resulting raw image to be. If this is different from the colortype of the
+PNG, then the decoder will automatically convert the result. This conversion
+always works, except if you want it to convert a color PNG to grayscale or to
+a palette with missing colors.
+
+By default, 32-bit color is used for the result.

+------------------------------
+
+The settings can be used to ignore the errors created by invalid CRC and Adler32
+chunks, and to disable the decoding of tEXt chunks.
+
+There's also a setting color_convert, true by default. If false, no conversion
+is done, the resulting data will be as it was in the PNG (after decompression)
+and you'll have to puzzle the colors of the pixels together yourself using the
+color type information in the LodePNGInfo.
+
+
+5. Encoding
+-----------
+
+Encoding converts a raw pixel buffer to a PNG compressed image.
+
+Most documentation on using the encoder is at its declarations in the header
+above. For C, simple encoding can be done with functions such as
+lodepng_encode32, and more advanced decoding can be done with the struct
+LodePNGState and lodepng_encode. For C++, all encoding can be done with the
+various lodepng::encode functions, and lodepng::State can be used for advanced
+features.
+
+Like the decoder, the encoder can also give errors. However it gives less errors
+since the encoder input is trusted, the decoder input (a PNG image that could
+be forged by anyone) is not trusted.
+
+When using the LodePNGState, it uses the following fields for encoding:
+*) LodePNGInfo info_png: here you specify how you want the PNG (the output) to be.
+*) LodePNGColorMode info_raw: here you say what color type of the raw image (the input) has
+*) LodePNGEncoderSettings encoder: you can specify a few settings for the encoder to use
+
+LodePNGInfo info_png
+--------------------
+
+When encoding, you use this the opposite way as when decoding: for encoding,
+you fill in the values you want the PNG to have before encoding. By default it's
+not needed to specify a color type for the PNG since it's automatically chosen,
+but it's possible to choose it yourself given the right settings.
+
+The encoder will not always exactly match the LodePNGInfo struct you give,
+it tries as close as possible. Some things are ignored by the encoder. The
+encoder uses, for example, the following settings from it when applicable:
+colortype and bitdepth, text chunks, time chunk, the color key, the palette, the
+background color, the interlace method, unknown chunks, ...
+
+When encoding to a PNG with colortype 3, the encoder will generate a PLTE chunk.
+If the palette contains any colors for which the alpha channel is not 255 (so
+there are translucent colors in the palette), it'll add a tRNS chunk.
+
+LodePNGColorMode info_raw
+-------------------------
+
+You specify the color type of the raw image that you give to the input here,
+including a possible transparent color key and palette you happen to be using in
+your raw image data.
+
+By default, 32-bit color is assumed, meaning your input has to be in RGBA
+format with 4 bytes (unsigned chars) per pixel.
+
+LodePNGEncoderSettings encoder
+------------------------------
+
+The following settings are supported (some are in sub-structs):
+*) auto_convert: when this option is enabled, the encoder will
+automatically choose the smallest possible color mode (including color key) that
+can encode the colors of all pixels without information loss.
+*) btype: the block type for LZ77. 0 = uncompressed, 1 = fixed huffman tree,
+   2 = dynamic huffman tree (best compression). Should be 2 for proper
+   compression.
+*) use_lz77: whether or not to use LZ77 for compressed block types. Should be
+   true for proper compression.
+*) windowsize: the window size used by the LZ77 encoder (1 - 32768). Has value
+   2048 by default, but can be set to 32768 for better, but slow, compression.
+*) force_palette: if colortype is 2 or 6, you can make the encoder write a PLTE
+   chunk if force_palette is true. This can used as suggested palette to convert
+   to by viewers that don't support more than 256 colors (if those still exist)
+*) add_id: add text chunk "Encoder: LodePNG <version>" to the image.
+*) text_compression: default 1. If 1, it'll store texts as zTXt instead of tEXt chunks.
+  zTXt chunks use zlib compression on the text. This gives a smaller result on
+  large texts but a larger result on small texts (such as a single program name).
+  It's all tEXt or all zTXt though, there's no separate setting per text yet.
+
+
+6. color conversions
+--------------------
+
+An important thing to note about LodePNG, is that the color type of the PNG, and
+the color type of the raw image, are completely independent. By default, when
+you decode a PNG, you get the result as a raw image in the color type you want,
+no matter whether the PNG was encoded with a palette, grayscale or RGBA color.
+And if you encode an image, by default LodePNG will automatically choose the PNG
+color type that gives good compression based on the values of colors and amount
+of colors in the image. It can be configured to let you control it instead as
+well, though.
+
+To be able to do this, LodePNG does conversions from one color mode to another.
+It can convert from almost any color type to any other color type, except the
+following conversions: RGB to grayscale is not supported, and converting to a
+palette when the palette doesn't have a required color is not supported. This is
+not supported on purpose: this is information loss which requires a color
+reduction algorithm that is beyond the scope of a PNG encoder (yes, RGB to gray
+is easy, but there are multiple ways if you want to give some channels more
+weight).
+
+By default, when decoding, you get the raw image in 32-bit RGBA or 24-bit RGB
+color, no matter what color type the PNG has. And by default when encoding,
+LodePNG automatically picks the best color model for the output PNG, and expects
+the input image to be 32-bit RGBA or 24-bit RGB. So, unless you want to control
+the color format of the images yourself, you can skip this chapter.
+
+6.1. PNG color types
+--------------------
+
+A PNG image can have many color types, ranging from 1-bit color to 64-bit color,
+as well as palettized color modes. After the zlib decompression and unfiltering
+in the PNG image is done, the raw pixel data will have that color type and thus
+a certain amount of bits per pixel. If you want the output raw image after
+decoding to have another color type, a conversion is done by LodePNG.
+
+The PNG specification gives the following color types:
+
+0: grayscale, bit depths 1, 2, 4, 8, 16
+2: RGB, bit depths 8 and 16
+3: palette, bit depths 1, 2, 4 and 8
+4: grayscale with alpha, bit depths 8 and 16
+6: RGBA, bit depths 8 and 16
+
+Bit depth is the amount of bits per pixel per color channel. So the total amount
+of bits per pixel is: amount of channels * bitdepth.
+
+6.2. color conversions
+----------------------
+
+As explained in the sections about the encoder and decoder, you can specify
+color types and bit depths in info_png and info_raw to change the default
+behaviour.
+
+If, when decoding, you want the raw image to be something else than the default,
+you need to set the color type and bit depth you want in the LodePNGColorMode,
+or the parameters colortype and bitdepth of the simple decoding function.
+
+If, when encoding, you use another color type than the default in the raw input
+image, you need to specify its color type and bit depth in the LodePNGColorMode
+of the raw image, or use the parameters colortype and bitdepth of the simple
+encoding function.
+
+If, when encoding, you don't want LodePNG to choose the output PNG color type
+but control it yourself, you need to set auto_convert in the encoder settings
+to false, and specify the color type you want in the LodePNGInfo of the
+encoder (including palette: it can generate a palette if auto_convert is true,
+otherwise not).
+
+If the input and output color type differ (whether user chosen or auto chosen),
+LodePNG will do a color conversion, which follows the rules below, and may
+sometimes result in an error.
+
+To avoid some confusion:
+-the decoder converts from PNG to raw image
+-the encoder converts from raw image to PNG
+-the colortype and bitdepth in LodePNGColorMode info_raw, are those of the raw image
+-the colortype and bitdepth in the color field of LodePNGInfo info_png, are those of the PNG
+-when encoding, the color type in LodePNGInfo is ignored if auto_convert
+ is enabled, it is automatically generated instead
+-when decoding, the color type in LodePNGInfo is set by the decoder to that of the original
+ PNG image, but it can be ignored since the raw image has the color type you requested instead
+-if the color type of the LodePNGColorMode and PNG image aren't the same, a conversion
+ between the color types is done if the color types are supported. If it is not
+ supported, an error is returned. If the types are the same, no conversion is done.
+-even though some conversions aren't supported, LodePNG supports loading PNGs from any
+ colortype and saving PNGs to any colortype, sometimes it just requires preparing
+ the raw image correctly before encoding.
+-both encoder and decoder use the same color converter.
+
+The function lodepng_convert does the color conversion. It is available in the
+interface but normally isn't needed since the encoder and decoder already call
+it.
+
+Non supported color conversions:
+-color to grayscale when non-gray pixels are present: no error is thrown, but
+the result will look ugly because only the red channel is taken (it assumes all
+three channels are the same in this case so ignores green and blue). The reason
+no error is given is to allow converting from three-channel grayscale images to
+one-channel even if there are numerical imprecisions.
+-anything to palette when the palette does not have an exact match for a from-color
+in it: in this case an error is thrown
+
+Supported color conversions:
+-anything to 8-bit RGB, 8-bit RGBA, 16-bit RGB, 16-bit RGBA
+-any gray or gray+alpha, to gray or gray+alpha
+-anything to a palette, as long as the palette has the requested colors in it
+-removing alpha channel
+-higher to smaller bitdepth, and vice versa
+
+If you want no color conversion to be done (e.g. for speed or control):
+-In the encoder, you can make it save a PNG with any color type by giving the
+raw color mode and LodePNGInfo the same color mode, and setting auto_convert to
+false.
+-In the decoder, you can make it store the pixel data in the same color type
+as the PNG has, by setting the color_convert setting to false. Settings in
+info_raw are then ignored.
+
+6.3. padding bits
+-----------------
+
+In the PNG file format, if a less than 8-bit per pixel color type is used and the scanlines
+have a bit amount that isn't a multiple of 8, then padding bits are used so that each
+scanline starts at a fresh byte. But that is NOT true for the LodePNG raw input and output.
+The raw input image you give to the encoder, and the raw output image you get from the decoder
+will NOT have these padding bits, e.g. in the case of a 1-bit image with a width
+of 7 pixels, the first pixel of the second scanline will the 8th bit of the first byte,
+not the first bit of a new byte.
+
+6.4. A note about 16-bits per channel and endianness
+----------------------------------------------------
+
+LodePNG uses unsigned char arrays for 16-bit per channel colors too, just like
+for any other color format. The 16-bit values are stored in big endian (most
+significant byte first) in these arrays. This is the opposite order of the
+little endian used by x86 CPU's.
+
+LodePNG always uses big endian because the PNG file format does so internally.
+Conversions to other formats than PNG uses internally are not supported by
+LodePNG on purpose, there are myriads of formats, including endianness of 16-bit
+colors, the order in which you store R, G, B and A, and so on. Supporting and
+converting to/from all that is outside the scope of LodePNG.
+
+This may mean that, depending on your use case, you may want to convert the big
+endian output of LodePNG to little endian with a for loop. This is certainly not
+always needed, many applications and libraries support big endian 16-bit colors
+anyway, but it means you cannot simply cast the unsigned char* buffer to an
+unsigned short* buffer on x86 CPUs.
+
+
+7. error values
+---------------
+
+All functions in LodePNG that return an error code, return 0 if everything went
+OK, or a non-zero code if there was an error.
+
+The meaning of the LodePNG error values can be retrieved with the function
+lodepng_error_text: given the numerical error code, it returns a description
+of the error in English as a string.
+
+Check the implementation of lodepng_error_text to see the meaning of each code.
+
+It is not recommended to use the numerical values to programmatically make
+different decisions based on error types as the numbers are not guaranteed to
+stay backwards compatible. They are for human consumption only. Programmatically
+only 0 or non-0 matter.
+
+
+8. chunks and PNG editing
+-------------------------
+
+If you want to add extra chunks to a PNG you encode, or use LodePNG for a PNG
+editor that should follow the rules about handling of unknown chunks, or if your
+program is able to read other types of chunks than the ones handled by LodePNG,
+then that's possible with the chunk functions of LodePNG.
+
+A PNG chunk has the following layout:
+
+4 bytes length
+4 bytes type name
+length bytes data
+4 bytes CRC
+
+8.1. iterating through chunks
+-----------------------------
+
+If you have a buffer containing the PNG image data, then the first chunk (the
+IHDR chunk) starts at byte number 8 of that buffer. The first 8 bytes are the
+signature of the PNG and are not part of a chunk. But if you start at byte 8
+then you have a chunk, and can check the following things of it.
+
+NOTE: none of these functions check for memory buffer boundaries. To avoid
+exploits, always make sure the buffer contains all the data of the chunks.
+When using lodepng_chunk_next, make sure the returned value is within the
+allocated memory.
+
+unsigned lodepng_chunk_length(const unsigned char* chunk):
+
+Get the length of the chunk's data. The total chunk length is this length + 12.
+
+void lodepng_chunk_type(char type[5], const unsigned char* chunk):
+unsigned char lodepng_chunk_type_equals(const unsigned char* chunk, const char* type):
+
+Get the type of the chunk or compare if it's a certain type
+
+unsigned char lodepng_chunk_critical(const unsigned char* chunk):
+unsigned char lodepng_chunk_private(const unsigned char* chunk):
+unsigned char lodepng_chunk_safetocopy(const unsigned char* chunk):
+
+Check if the chunk is critical in the PNG standard (only IHDR, PLTE, IDAT and IEND are).
+Check if the chunk is private (public chunks are part of the standard, private ones not).
+Check if the chunk is safe to copy. If it's not, then, when modifying data in a critical
+chunk, unsafe to copy chunks of the old image may NOT be saved in the new one if your
+program doesn't handle that type of unknown chunk.
+
+unsigned char* lodepng_chunk_data(unsigned char* chunk):
+const unsigned char* lodepng_chunk_data_const(const unsigned char* chunk):
+
+Get a pointer to the start of the data of the chunk.
+
+unsigned lodepng_chunk_check_crc(const unsigned char* chunk):
+void lodepng_chunk_generate_crc(unsigned char* chunk):
+
+Check if the crc is correct or generate a correct one.
+
+unsigned char* lodepng_chunk_next(unsigned char* chunk):
+const unsigned char* lodepng_chunk_next_const(const unsigned char* chunk):
+
+Iterate to the next chunk. This works if you have a buffer with consecutive chunks. Note that these
+functions do no boundary checking of the allocated data whatsoever, so make sure there is enough
+data available in the buffer to be able to go to the next chunk.
+
+unsigned lodepng_chunk_append(unsigned char** out, size_t* outsize, const unsigned char* chunk):
+unsigned lodepng_chunk_create(unsigned char** out, size_t* outsize, unsigned length,
+                              const char* type, const unsigned char* data):
+
+These functions are used to create new chunks that are appended to the data in *out that has
+length *outsize. The append function appends an existing chunk to the new data. The create
+function creates a new chunk with the given parameters and appends it. Type is the 4-letter
+name of the chunk.
+
+8.2. chunks in info_png
+-----------------------
+
+The LodePNGInfo struct contains fields with the unknown chunk in it. It has 3
+buffers (each with size) to contain 3 types of unknown chunks:
+the ones that come before the PLTE chunk, the ones that come between the PLTE
+and the IDAT chunks, and the ones that come after the IDAT chunks.
+It's necessary to make the distinction between these 3 cases because the PNG
+standard forces to keep the ordering of unknown chunks compared to the critical
+chunks, but does not force any other ordering rules.
+
+info_png.unknown_chunks_data[0] is the chunks before PLTE
+info_png.unknown_chunks_data[1] is the chunks after PLTE, before IDAT
+info_png.unknown_chunks_data[2] is the chunks after IDAT
+
+The chunks in these 3 buffers can be iterated through and read by using the same
+way described in the previous subchapter.
+
+When using the decoder to decode a PNG, you can make it store all unknown chunks
+if you set the option settings.remember_unknown_chunks to 1. By default, this
+option is off (0).
+
+The encoder will always encode unknown chunks that are stored in the info_png.
+If you need it to add a particular chunk that isn't known by LodePNG, you can
+use lodepng_chunk_append or lodepng_chunk_create to the chunk data in
+info_png.unknown_chunks_data[x].
+
+Chunks that are known by LodePNG should not be added in that way. E.g. to make
+LodePNG add a bKGD chunk, set background_defined to true and add the correct
+parameters there instead.
+
+
+9. compiler support
+-------------------
+
+No libraries other than the current standard C library are needed to compile
+LodePNG. For the C++ version, only the standard C++ library is needed on top.
+Add the files lodepng.c(pp) and lodepng.h to your project, include
+lodepng.h where needed, and your program can read/write PNG files.
+
+It is compatible with C90 and up, and C++03 and up.
+
+If performance is important, use optimization when compiling! For both the
+encoder and decoder, this makes a large difference.
+
+Make sure that LodePNG is compiled with the same compiler of the same version
+and with the same settings as the rest of the program, or the interfaces with
+std::vectors and std::strings in C++ can be incompatible.
+
+CHAR_BITS must be 8 or higher, because LodePNG uses unsigned chars for octets.
+
+*) gcc and g++
+
+LodePNG is developed in gcc so this compiler is natively supported. It gives no
+warnings with compiler options "-Wall -Wextra -pedantic -ansi", with gcc and g++
+version 4.7.1 on Linux, 32-bit and 64-bit.
+
+*) Clang
+
+Fully supported and warning-free.
+
+*) Mingw
+
+The Mingw compiler (a port of gcc for Windows) should be fully supported by
+LodePNG.
+
+*) Visual Studio and Visual C++ Express Edition
+
+LodePNG should be warning-free with warning level W4. Two warnings were disabled
+with pragmas though: warning 4244 about implicit conversions, and warning 4996
+where it wants to use a non-standard function fopen_s instead of the standard C
+fopen.
+
+Visual Studio may want "stdafx.h" files to be included in each source file and
+give an error "unexpected end of file while looking for precompiled header".
+This is not standard C++ and will not be added to the stock LodePNG. You can
+disable it for lodepng.cpp only by right clicking it, Properties, C/C++,
+Precompiled Headers, and set it to Not Using Precompiled Headers there.
+
+NOTE: Modern versions of VS should be fully supported, but old versions, e.g.
+VS6, are not guaranteed to work.
+
+*) Compilers on Macintosh
+
+LodePNG has been reported to work both with gcc and LLVM for Macintosh, both for
+C and C++.
+
+*) Other Compilers
+
+If you encounter problems on any compilers, feel free to let me know and I may
+try to fix it if the compiler is modern and standards compliant.
+
+
+10. examples
+------------
+
+This decoder example shows the most basic usage of LodePNG. More complex
+examples can be found on the LodePNG website.
+
+NOTE: these examples do not support wide-character filenames, you can use an
+external method to handle such files and encode or decode in-memory
+
+10.1. decoder C++ example
+-------------------------
+
+#include "lodepng.h"
+#include <iostream>
+
+int main(int argc, char *argv[]) {
+  const char* filename = argc > 1 ? argv[1] : "test.png";
+
+  //load and decode
+  std::vector<unsigned char> image;
+  unsigned width, height;
+  unsigned error = lodepng::decode(image, width, height, filename);
+
+  //if there's an error, display it
+  if(error) std::cout << "decoder error " << error << ": " << lodepng_error_text(error) << std::endl;
+
+  //the pixels are now in the vector "image", 4 bytes per pixel, ordered RGBARGBA..., use it as texture, draw it, ...
+}
+
+10.2. decoder C example
+-----------------------
+
+#include "lodepng.h"
+
+int main(int argc, char *argv[]) {
+  unsigned error;
+  unsigned char* image;
+  size_t width, height;
+  const char* filename = argc > 1 ? argv[1] : "test.png";
+
+  error = lodepng_decode32_file(&image, &width, &height, filename);
+
+  if(error) printf("decoder error %u: %s\n", error, lodepng_error_text(error));
+
+  / * use image here * /
+
+  free(image);
+  return 0;

+    (no palette). Better deflate tree encoding. New compression tweak settings.
+    Faster color conversions while decoding. Some internal cleanups.
+*) 23 sep 2012: Reduced warnings in Visual Studio a little bit.
+*) 1 sep 2012: (!) Removed #define's for giving custom (de)compression functions
+    and made it work with function pointers instead.
+*) 23 jun 2012: Added more filter strategies. Made it easier to use custom alloc
+    and free functions and toggle #defines from compiler flags. Small fixes.
+*) 6 may 2012: (!) Made plugging in custom zlib/deflate functions more flexible.
+*) 22 apr 2012: (!) Made interface more consistent, renaming a lot. Removed
+    redundant C++ codec classes. Reduced amount of structs. Everything changed,
+    but it is cleaner now imho and functionality remains the same. Also fixed
+    several bugs and shrunk the implementation code. Made new samples.
+*) 6 nov 2011: (!) By default, the encoder now automatically chooses the best
+    PNG color model and bit depth, based on the amount and type of colors of the
+    raw image. For this, autoLeaveOutAlphaChannel replaced by auto_choose_color.
+*) 9 okt 2011: simpler hash chain implementation for the encoder.
+*) 8 sep 2011: lz77 encoder lazy matching instead of greedy matching.
+*) 23 aug 2011: tweaked the zlib compression parameters after benchmarking.
+    A bug with the PNG filtertype heuristic was fixed, so that it chooses much
+    better ones (it's quite significant). A setting to do an experimental, slow,
+    brute force search for PNG filter types is added.
+*) 17 aug 2011: (!) changed some C zlib related function names.
+*) 16 aug 2011: made the code less wide (max 120 characters per line).
+*) 17 apr 2011: code cleanup. Bugfixes. Convert low to 16-bit per sample colors.
+*) 21 feb 2011: fixed compiling for C90. Fixed compiling with sections disabled.
+*) 11 dec 2010: encoding is made faster, based on suggestion by Peter Eastman
+    to optimize long sequences of zeros.
+*) 13 nov 2010: added LodePNG_InfoColor_hasPaletteAlpha and
+    LodePNG_InfoColor_canHaveAlpha functions for convenience.
+*) 7 nov 2010: added LodePNG_error_text function to get error code description.
+*) 30 okt 2010: made decoding slightly faster
+*) 26 okt 2010: (!) changed some C function and struct names (more consistent).
+     Reorganized the documentation and the declaration order in the header.
+*) 08 aug 2010: only changed some comments and external samples.
+*) 05 jul 2010: fixed bug thanks to warnings in the new gcc version.
+*) 14 mar 2010: fixed bug where too much memory was allocated for char buffers.
+*) 02 sep 2008: fixed bug where it could create empty tree that linux apps could
+    read by ignoring the problem but windows apps couldn't.
+*) 06 jun 2008: added more error checks for out of memory cases.
+*) 26 apr 2008: added a few more checks here and there to ensure more safety.
+*) 06 mar 2008: crash with encoding of strings fixed
+*) 02 feb 2008: support for international text chunks added (iTXt)
+*) 23 jan 2008: small cleanups, and #defines to divide code in sections
+*) 20 jan 2008: support for unknown chunks allowing using LodePNG for an editor.
+*) 18 jan 2008: support for tIME and pHYs chunks added to encoder and decoder.
+*) 17 jan 2008: ability to encode and decode compressed zTXt chunks added
+    Also various fixes, such as in the deflate and the padding bits code.
+*) 13 jan 2008: Added ability to encode Adam7-interlaced images. Improved
+    filtering code of encoder.
+*) 07 jan 2008: (!) changed LodePNG to use ISO C90 instead of C++. A
+    C++ wrapper around this provides an interface almost identical to before.
+    Having LodePNG be pure ISO C90 makes it more portable. The C and C++ code
+    are together in these files but it works both for C and C++ compilers.
+*) 29 dec 2007: (!) changed most integer types to unsigned int + other tweaks
+*) 30 aug 2007: bug fixed which makes this Borland C++ compatible
+*) 09 aug 2007: some VS2005 warnings removed again
+*) 21 jul 2007: deflate code placed in new namespace separate from zlib code
+*) 08 jun 2007: fixed bug with 2- and 4-bit color, and small interlaced images
+*) 04 jun 2007: improved support for Visual Studio 2005: crash with accessing
+    invalid std::vector element [0] fixed, and level 3 and 4 warnings removed
+*) 02 jun 2007: made the encoder add a tag with version by default
+*) 27 may 2007: zlib and png code separated (but still in the same file),
+    simple encoder/decoder functions added for more simple usage cases
+*) 19 may 2007: minor fixes, some code cleaning, new error added (error 69),
+    moved some examples from here to lodepng_examples.cpp
+*) 12 may 2007: palette decoding bug fixed
+*) 24 apr 2007: changed the license from BSD to the zlib license
+*) 11 mar 2007: very simple addition: ability to encode bKGD chunks.
+*) 04 mar 2007: (!) tEXt chunk related fixes, and support for encoding
+    palettized PNG images. Plus little interface change with palette and texts.
+*) 03 mar 2007: Made it encode dynamic Huffman shorter with repeat codes.
+    Fixed a bug where the end code of a block had length 0 in the Huffman tree.
+*) 26 feb 2007: Huffman compression with dynamic trees (BTYPE 2) now implemented
+    and supported by the encoder, resulting in smaller PNGs at the output.
+*) 27 jan 2007: Made the Adler-32 test faster so that a timewaste is gone.
+*) 24 jan 2007: gave encoder an error interface. Added color conversion from any
+    greyscale type to 8-bit greyscale with or without alpha.
+*) 21 jan 2007: (!) Totally changed the interface. It allows more color types
+    to convert to and is more uniform. See the manual for how it works now.
+*) 07 jan 2007: Some cleanup & fixes, and a few changes over the last days:
+    encode/decode custom tEXt chunks, separate classes for zlib & deflate, and
+    at last made the decoder give errors for incorrect Adler32 or Crc.
+*) 01 jan 2007: Fixed bug with encoding PNGs with less than 8 bits per channel.
+*) 29 dec 2006: Added support for encoding images without alpha channel, and
+    cleaned out code as well as making certain parts faster.
+*) 28 dec 2006: Added "Settings" to the encoder.
+*) 26 dec 2006: The encoder now does LZ77 encoding and produces much smaller files now.
+    Removed some code duplication in the decoder. Fixed little bug in an example.
+*) 09 dec 2006: (!) Placed output parameters of public functions as first parameter.
+    Fixed a bug of the decoder with 16-bit per color.
+*) 15 okt 2006: Changed documentation structure
+*) 09 okt 2006: Encoder class added. It encodes a valid PNG image from the
+    given image buffer, however for now it's not compressed.
+*) 08 sep 2006: (!) Changed to interface with a Decoder class
+*) 30 jul 2006: (!) LodePNG_InfoPng , width and height are now retrieved in different
+    way. Renamed decodePNG to decodePNGGeneric.
+*) 29 jul 2006: (!) Changed the interface: image info is now returned as a
+    struct of type LodePNG::LodePNG_Info, instead of a vector, which was a bit clumsy.
+*) 28 jul 2006: Cleaned the code and added new error checks.
+    Corrected terminology "deflate" into "inflate".
+*) 23 jun 2006: Added SDL example in the documentation in the header, this
+    example allows easy debugging by displaying the PNG and its transparency.
+*) 22 jun 2006: (!) Changed way to obtain error value. Added
+    loadFile function for convenience. Made decodePNG32 faster.
+*) 21 jun 2006: (!) Changed type of info vector to unsigned.
+    Changed position of palette in info vector. Fixed an important bug that
+    happened on PNGs with an uncompressed block.
+*) 16 jun 2006: Internally changed unsigned into unsigned where
+    needed, and performed some optimizations.
+*) 07 jun 2006: (!) Renamed functions to decodePNG and placed them
+    in LodePNG namespace. Changed the order of the parameters. Rewrote the
+    documentation in the header. Renamed files to lodepng.cpp and lodepng.h
+*) 22 apr 2006: Optimized and improved some code
+*) 07 sep 2005: (!) Changed to std::vector interface
+*) 12 aug 2005: Initial release (C++, decoder only)

-// COMPILE-TIME OPTIONS FOR DEAR IMGUI
-// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
-// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
-//-----------------------------------------------------------------------------
-// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
-// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
-//-----------------------------------------------------------------------------
-// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
-// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
-// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
-// Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using.

-//#define IMGUI_DISABLE_SSE                                 // Disable use of SSE intrinsics even if available
-
-//---- Include imgui_user.h at the end of imgui.h as a convenience
-//#define IMGUI_INCLUDE_IMGUI_USER_H
-
-//---- Pack colors to BGRA8 instead of RGBA8 (to avoid converting from one to another)
-//#define IMGUI_USE_BGRA_PACKED_COLOR
-
-//---- Use 32-bit for ImWchar (default is 16-bit) to support unicode planes 1-16. (e.g. point beyond 0xFFFF like emoticons, dingbats, symbols, shapes, ancient languages, etc...)
-//#define IMGUI_USE_WCHAR32
-
-//---- Avoid multiple STB libraries implementations, or redefine path/filenames to prioritize another version
-// By default the embedded implementations are declared static and not available outside of Dear ImGui sources files.
-//#define IMGUI_STB_TRUETYPE_FILENAME   "my_folder/stb_truetype.h"
-//#define IMGUI_STB_RECT_PACK_FILENAME  "my_folder/stb_rect_pack.h"
-//#define IMGUI_DISABLE_STB_TRUETYPE_IMPLEMENTATION
-//#define IMGUI_DISABLE_STB_RECT_PACK_IMPLEMENTATION
-
-//---- Use stb_printf's faster implementation of vsnprintf instead of the one from libc (unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)
-// Requires 'stb_sprintf.h' to be available in the include path. Compatibility checks of arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by STB sprintf.
-// #define IMGUI_USE_STB_SPRINTF
-
-//---- Use FreeType to build and rasterize the font atlas (instead of stb_truetype which is embedded by default in Dear ImGui)
-// Requires FreeType headers to be available in the include path. Requires program to be compiled with 'misc/freetype/imgui_freetype.cpp' (in this repository) + the FreeType library (not provided).
-// On Windows you may use vcpkg with 'vcpkg install freetype --triplet=x64-windows' + 'vcpkg integrate install'.
-//#define IMGUI_ENABLE_FREETYPE
-
-//---- Use stb_truetype to build and rasterize the font atlas (default)
-// The only purpose of this define is if you want force compilation of the stb_truetype backend ALONG with the FreeType backend.
-//#define IMGUI_ENABLE_STB_TRUETYPE
-
-//---- Define constructor and implicit cast operators to convert back<>forth between your math types and ImVec2/ImVec4.
-// This will be inlined as part of ImVec2 and ImVec4 class declarations.
-/*
-#define IM_VEC2_CLASS_EXTRA                                                 \
-        ImVec2(const MyVec2& f) { x = f.x; y = f.y; }                       \
-        operator MyVec2() const { return MyVec2(x,y); }
-
-#define IM_VEC4_CLASS_EXTRA                                                 \
-        ImVec4(const MyVec4& f) { x = f.x; y = f.y; z = f.z; w = f.w; }     \
-        operator MyVec4() const { return MyVec4(x,y,z,w); }
-*/
-
-//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
-// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
-// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
-// Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
-//#define ImDrawIdx unsigned int
-
-//---- Override ImDrawCallback signature (will need to modify renderer backends accordingly)
-//struct ImDrawList;
-//struct ImDrawCmd;
-//typedef void (*MyImDrawCallback)(const ImDrawList* draw_list, const ImDrawCmd* cmd, void* my_renderer_user_data);
-//#define ImDrawCallback MyImDrawCallback
-
-//---- Debug Tools: Macro to break in Debugger
-// (use 'Metrics->Tools->Item Picker' to pick widgets with the mouse and break into them for easy debugging.)
-//#define IM_DEBUG_BREAK  IM_ASSERT(0)
-//#define IM_DEBUG_BREAK  __debugbreak()
-
-//---- Debug Tools: Have the Item Picker break in the ItemAdd() function instead of ItemHoverable(),
-// (which comes earlier in the code, will catch a few extra items, allow picking items other than Hovered one.)
-// This adds a small runtime cost which is why it is not enabled by default.
-//#define IMGUI_DEBUG_TOOL_ITEM_PICKER_EX
-
-//---- Debug Tools: Enable slower asserts
-//#define IMGUI_DEBUG_PARANOID
-
-//---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.

- MISSION STATEMENT
- =================
-
- - Easy to use to create code-driven and data-driven tools.
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
- - Easy to hack and improve.
- - Minimize setup and maintenance.
- - Minimize state storage on user side.
- - Portable, minimize dependencies, run on target (consoles, phones, etc.).
- - Efficient runtime and memory consumption.
-
- Designed for developers and content-creators, not the typical end-user! Some of the current weaknesses includes:
-
- - Doesn't look fancy, doesn't animate.
- - Limited layout features, intricate layouts are typically crafted in code.
-
-
- END-USER GUIDE
- ==============
-
- - Double-click on title bar to collapse window.
- - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().
- - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).
- - Click and drag on any empty space to move window.
- - TAB/SHIFT+TAB to cycle through keyboard editable fields.
- - CTRL+Click on a slider or drag box to input value as text.
- - Use mouse wheel to scroll.
- - Text editor:
-   - Hold SHIFT or use mouse to select text.
-   - CTRL+Left/Right to word jump.
-   - CTRL+Shift+Left/Right to select words.
-   - CTRL+A our Double-Click to select all.
-   - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/
-   - CTRL+Z,CTRL+Y to undo/redo.
-   - ESCAPE to revert text to its original value.
-   - Controls are automatically adjusted for OSX to match standard OSX text editing operations.
- - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.
- - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://dearimgui.org/controls_sheets

- PROGRAMMER GUIDE
- ================
-
- READ FIRST
- ----------
- - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki)
- - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or
-   destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs.
- - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
- - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
-   You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki.
- - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
-   For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,
-   where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
- - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- - This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
- - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
-   If you get an assert, read the messages and comments around the assert.
- - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
- - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
-   See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
-   However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
- - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
-
-
- HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
- ----------------------------------------------
- - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h)
- - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master".
- - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.
- - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
-   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
-   from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
-   likely be a comment about it. Please report any issue to the GitHub page!
- - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.
- - Try to keep your copy of Dear ImGui reasonably up to date.
-
-
- GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
- ---------------------------------------------------------------
- - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
- - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
-   It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL).
- - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
- - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
-   Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
-   phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render().
- - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.
- - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
-
-
- HOW A SIMPLE APPLICATION MAY LOOK LIKE
- --------------------------------------
- EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder).
- The sub-folders in examples/ contain examples applications following this structure.
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
-     ImGui_ImplWin32_Init(hwnd);
-     ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
-
-     // Application main loop
-     while (true)
-     {
-         // Feed inputs to dear imgui, start new frame
-         ImGui_ImplDX11_NewFrame();
-         ImGui_ImplWin32_NewFrame();
-         ImGui::NewFrame();
-
-         // Any application code here
-         ImGui::Text("Hello, world!");
-
-         // Render dear imgui into screen
-         ImGui::Render();
-         ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
-         g_pSwapChain->Present(1, 0);
-     }
-
-     // Shutdown
-     ImGui_ImplDX11_Shutdown();
-     ImGui_ImplWin32_Shutdown();
-     ImGui::DestroyContext();
-
- EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Build and load the texture atlas into a texture
-     // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)
-     int width, height;
-     unsigned char* pixels = NULL;
-     io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
-
-     // At this point you've got the texture data and you need to upload that to your graphic system:
-     // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
-     // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
-     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
-     io.Fonts->SetTexID((void*)texture);
-
-     // Application main loop
-     while (true)
-     {
-        // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
-        // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform Backends)
-        io.DeltaTime = 1.0f/60.0f;              // set the time elapsed since the previous frame (in seconds)
-        io.DisplaySize.x = 1920.0f;             // set the current display width
-        io.DisplaySize.y = 1280.0f;             // set the current display height here
-        io.AddMousePosEvent(mouse_x, mouse_y);  // update mouse position
-        io.AddMouseButtonEvent(0, mouse_b[0]);  // update mouse button states
-        io.AddMouseButtonEvent(1, mouse_b[1]);  // update mouse button states
-
-        // Call NewFrame(), after this point you can use ImGui::* functions anytime
-        // (So you want to try calling NewFrame() as early as you can in your main loop to be able to use Dear ImGui everywhere)
-        ImGui::NewFrame();
-
-        // Most of your application code here
-        ImGui::Text("Hello, world!");
-        MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
-        MyGameRender(); // may use any Dear ImGui functions as well!
-
-        // Render dear imgui, swap buffers
-        // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
-        ImGui::EndFrame();
-        ImGui::Render();
-        ImDrawData* draw_data = ImGui::GetDrawData();
-        MyImGuiRenderFunction(draw_data);
-        SwapBuffers();
-     }
-
-     // Shutdown
-     ImGui::DestroyContext();
-
- To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application,
- you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- Please read the FAQ and example applications for details about this!
-
-
- HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE
- ---------------------------------------------
- The backends in impl_impl_XXX.cpp files contain many working implementations of a rendering function.
-
-    void void MyImGuiRenderFunction(ImDrawData* draw_data)
-    {
-       // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
-       // TODO: Setup viewport covering draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
-       // TODO: Setup orthographic projection matrix cover draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
-       // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
-       ImVec2 clip_off = draw_data->DisplayPos;
-       for (int n = 0; n < draw_data->CmdListsCount; n++)
-       {
-          const ImDrawList* cmd_list = draw_data->CmdLists[n];
-          const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data;  // vertex buffer generated by Dear ImGui
-          const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data;   // index buffer generated by Dear ImGui
-          for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)
-          {
-             const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];
-             if (pcmd->UserCallback)
-             {
-                 pcmd->UserCallback(cmd_list, pcmd);
-             }
-             else
-             {
-                 // Project scissor/clipping rectangles into framebuffer space
-                 ImVec2 clip_min(pcmd->ClipRect.x - clip_off.x, pcmd->ClipRect.y - clip_off.y);
-                 ImVec2 clip_max(pcmd->ClipRect.z - clip_off.x, pcmd->ClipRect.w - clip_off.y);
-                 if (clip_max.x <= clip_min.x || clip_max.y <= clip_min.y)
-                     continue;
-
-                 // We are using scissoring to clip some objects. All low-level graphics API should support it.
-                 // - If your engine doesn't support scissoring yet, you may ignore this at first. You will get some small glitches
-                 //   (some elements visible outside their bounds) but you can fix that once everything else works!
-                 // - Clipping coordinates are provided in imgui coordinates space:
-                 //   - For a given viewport, draw_data->DisplayPos == viewport->Pos and draw_data->DisplaySize == viewport->Size
-                 //   - In a single viewport application, draw_data->DisplayPos == (0,0) and draw_data->DisplaySize == io.DisplaySize, but always use GetMainViewport()->Pos/Size instead of hardcoding those values.
-                 //   - In the interest of supporting multi-viewport applications (see 'docking' branch on github),
-                 //     always subtract draw_data->DisplayPos from clipping bounds to convert them to your viewport space.
-                 // - Note that pcmd->ClipRect contains Min+Max bounds. Some graphics API may use Min+Max, other may use Min+Size (size being Max-Min)
-                 MyEngineSetScissor(clip_min.x, clip_min.y, clip_max.x, clip_max.y);
-
-                 // The texture for the draw call is specified by pcmd->GetTexID().
-                 // The vast majority of draw calls will use the Dear ImGui texture atlas, which value you have set yourself during initialization.
-                 MyEngineBindTexture((MyTexture*)pcmd->GetTexID());

- USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
- ------------------------------------------
- - The gamepad/keyboard navigation is fairly functional and keeps being improved.
- - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!
- - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
- - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
- - Keyboard:
-    - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
-    - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() calls.
-    - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard),
-      the io.WantCaptureKeyboard flag will be set. For more advanced uses, you may want to read from:
-       - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
-       - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
-       - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
-      Please reach out if you think the game vs navigation input sharing could be improved.
- - Gamepad:
-    - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
-    - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
-      For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
-      Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
-    - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() + io.AddKeyAnalogEvent() calls.
-    - BEFORE 1.87, BACKENDS USED TO WRITE DIRECTLY TO io.NavInputs[]. This is going to be obsoleted in the future. Please call io functions instead!
-    - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets
-    - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,
-      with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
- - Mouse:
-    - PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
-    - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
-    - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
-      Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.
-      When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
-      When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that.
-      (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse moving back and forth!)
-      (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
-       to set a boolean to ignore your other external mouse positions until the external source is moved again.)

- API BREAKING CHANGES
- ====================
-
- Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
- Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
- When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
- You can read releases logs https://github.com/ocornut/imgui/releases for more details.
-
- - 2022/01/20 (1.87) - inputs: reworded gamepad IO.
-                        - Backend writing to io.NavInputs[]            -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values.
- - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).
- - 2022/01/17 (1.87) - inputs: reworked mouse IO.
-                        - Backend writing to io.MousePos               -> backend should call io.AddMousePosEvent()
-                        - Backend writing to io.MouseDown[]            -> backend should call io.AddMouseButtonEvent()
-                        - Backend writing to io.MouseWheel             -> backend should call io.AddMouseWheelEvent()
-                        - Backend writing to io.MouseHoveredViewport   -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only]
- - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.
-                        - IsKeyPressed(MY_NATIVE_KEY_XXX)              -> use IsKeyPressed(ImGuiKey_XXX)
-                        - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX))      -> use IsKeyPressed(ImGuiKey_XXX)
-                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent()
-                        - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiKey_ModXXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiKey_ModXXX values.*
-                     - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
-                     - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
- - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.
- - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
- - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019)
-                        - ImGui::SetNextTreeNodeOpen()        -> use ImGui::SetNextItemOpen()
-                        - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x
-                        - ImGui::TreeAdvanceToLabelPos()      -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());
-                        - ImFontAtlas::CustomRect             -> use ImFontAtlasCustomRect
-                        - ImGuiColorEditFlags_RGB/HSV/HEX     -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex
- - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings
- - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function.
- - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful.
- - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
-                        - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
-                        - ImFont::GlyphRangesBuilder  -> use ImFontGlyphRangesBuilder
- - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID().
-                        - if you are using official backends from the source tree: you have nothing to do.
-                        - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().
- - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags.
-                        - ImDrawCornerFlags_TopLeft  -> use ImDrawFlags_RoundCornersTopLeft
-                        - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight
-                        - ImDrawCornerFlags_None     -> use ImDrawFlags_RoundCornersNone etc.
-                       flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API.
-                       breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners":
-                        - rounding == 0.0f + flags == 0 --> meant no rounding  --> unchanged (common use)
-                        - rounding  > 0.0f + flags != 0 --> meant rounding     --> unchanged (common use)
-                        - rounding == 0.0f + flags != 0 --> meant no rounding  --> unchanged (unlikely use)
-                        - rounding  > 0.0f + flags == 0 --> meant no rounding  --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f.
-                       this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok.
-                       the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts.
-                       legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise).
- - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):
-                        - ImGui::SetScrollHere()              -> use ImGui::SetScrollHereY()
- - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing.
- - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file  with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
- - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
- - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
-                     - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).
-                     - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete).
- - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.
-                     - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.
-                     - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018):
-                        - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
-                        - ImGuiCol_ModalWindowDarkening       -> use ImGuiCol_ModalWindowDimBg
-                        - ImGuiInputTextCallback              -> use ImGuiTextEditCallback
-                        - ImGuiInputTextCallbackData          -> use ImGuiTextEditCallbackData
- - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).
- - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added!
- - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.
- - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures
- - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018):
-                        - io.RenderDrawListsFn pointer        -> use ImGui::GetDrawData() value and call the render function of your backend
-                        - ImGui::IsAnyWindowFocused()         -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)
-                        - ImGui::IsAnyWindowHovered()         -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
-                        - ImGuiStyleVar_Count_                -> use ImGuiStyleVar_COUNT
-                        - ImGuiMouseCursor_Count_             -> use ImGuiMouseCursor_COUNT
-                      - removed redirecting functions names that were marked obsolete in 1.61 (May 2018):
-                        - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision.
-                        - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
- - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).
- - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).
- - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
- - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.
- - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.
- - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now!
- - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().
-                       replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).
-                       worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:
-                       - if you omitted the 'power' parameter (likely!), you are not affected.
-                       - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.
-                       - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.
-                       see https://github.com/ocornut/imgui/issues/3361 for all details.
-                       kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
-                       for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
-                     - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.
- - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]
- - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
- - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().
- - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
- - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
- - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
- - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
-                       - ShowTestWindow()                    -> use ShowDemoWindow()
-                       - IsRootWindowFocused()               -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
-                       - IsRootWindowOrAnyChildFocused()     -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
-                       - SetNextWindowContentWidth(w)        -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
-                       - GetItemsLineHeightWithSpacing()     -> use GetFrameHeightWithSpacing()
-                       - ImGuiCol_ChildWindowBg              -> use ImGuiCol_ChildBg
-                       - ImGuiStyleVar_ChildWindowRounding   -> use ImGuiStyleVar_ChildRounding
-                       - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
-                       - IMGUI_DISABLE_TEST_WINDOWS          -> use IMGUI_DISABLE_DEMO_WINDOWS
- - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API.
- - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
- - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
- - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
-                       - Begin() [old 5 args version]        -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
-                       - IsRootWindowOrAnyChildHovered()     -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
-                       - AlignFirstTextHeightToWidgets()     -> use AlignTextToFramePadding()
-                       - SetNextWindowPosCenter()            -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
-                       - ImFont::Glyph                       -> use ImFontGlyph
- - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
-                       if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
-                       The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
-                       If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
- - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
- - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
- - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
- - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
-                       overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
-                       This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
-                       Please reach out if you are affected.
- - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
- - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
- - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
- - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
- - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
- - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
- - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value!
- - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
- - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
- - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
- - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
- - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
- - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
- - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
- - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
-                       If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
- - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
- - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
-                       NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
-                       Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
- - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
- - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
- - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
- - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
- - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
- - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
- - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.).
-                       old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports.
-                       when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call.
-                       in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
- - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
- - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
- - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
-                       If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
-                       To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
-                       If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
- - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
-                       consistent with other functions. Kept redirection functions (will obsolete).
- - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
- - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch).
- - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
- - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
- - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
- - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
- - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
-                       - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
-                       - removed Shutdown() function, as DestroyContext() serve this purpose.
-                       - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
-                       - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
-                       - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
- - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
- - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
- - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
- - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
- - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
- - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
- - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
- - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
-                     - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
- - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
- - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
- - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
- - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
-                       Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
- - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
- - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
- - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
- - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
- - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
- - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
- - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
-                       removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
-                         IsItemHoveredRect()        --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
-                         IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
-                         IsMouseHoveringWindow()    --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
- - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
- - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
- - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
- - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
- - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
- - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
-                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
-                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
- - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
- - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
- - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
- - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
- - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
-                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
-                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'
- - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
- - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
- - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
- - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild().
- - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
- - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
- - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal.
- - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
-                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
-                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
-                       ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
-                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
- - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337).
- - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
- - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
- - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
- - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
- - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
-                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
-                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
- - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
- - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
-                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
- - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
-                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
-                     - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
-                     - the signature of the io.RenderDrawListsFn handler has changed!
-                       old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
-                       new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
-                         parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
-                         ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
-                         ImDrawCmd:  'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
-                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
-                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
-                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
- - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
- - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
- - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
- - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
- - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry!
- - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
- - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
- - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
- - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
- - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
- - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
- - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
- - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
- - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
- - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
- - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
- - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
- - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
-                       - old:  const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];
-                       - new:  unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier);
-                       you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.
- - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID()
- - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
- - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite

- Q&A: Community
- ==============
-
- Q: How can I help?
- A: - Businesses: please reach out to "contact AT dearimgui.com" if you work in a place using Dear ImGui!
-      We can discuss ways for your company to fund development via invoiced technical support, maintenance or sponsoring contacts.
-      This is among the most useful thing you can do for Dear ImGui. With increased funding, we can hire more people working on this project.
-    - Individuals: you can support continued development via PayPal donations. See README.
-    - If you are experienced with Dear ImGui and C++, look at the GitHub issues, look at the Wiki, read docs/TODO.txt
-      and see how you want to help and can help!
-    - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
-      You may post screenshot or links in the gallery threads. Visuals are ideal as they inspire other programmers.
-      But even without visuals, disclosing your use of dear imgui helps the library grow credibility, and help other teams and programmers with taking decisions.
-    - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on GitHub or privately).

-// DLL users:
-// - Heaps and globals are not shared across DLL boundaries!
-// - You will need to call SetCurrentContext() + SetAllocatorFunctions() for each static/DLL boundary you are calling from.
-// - Same applies for hot-reloading mechanisms that are reliant on reloading DLL (note that many hot-reloading mechanisms work without DLL).
-// - Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
-// - Confused? In a debugger: add GImGui to your watch window and notice how its value changes depending on your current location (which DLL boundary you are in).
-
-// Current context pointer. Implicitly used by all Dear ImGui functions. Always assumed to be != NULL.
-// - ImGui::CreateContext() will automatically set this pointer if it is NULL.
-//   Change to a different context by calling ImGui::SetCurrentContext().
-// - Important: Dear ImGui functions are not thread-safe because of this pointer.
-//   If you want thread-safety to allow N threads to access N different contexts:
-//   - Change this variable to use thread local storage so each thread can refer to a different context, in your imconfig.h:
-//         struct ImGuiContext;
-//         extern thread_local ImGuiContext* MyImGuiTLS;
-//         #define GImGui MyImGuiTLS
-//     And then define MyImGuiTLS in one of your cpp files. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
-//   - Future development aims to make this context pointer explicit to all calls. Also read https://github.com/ocornut/imgui/issues/586
-//   - If you need a finite number of contexts, you may compile and use multiple instances of the ImGui code from a different namespace.
-// - DLL users: read comments above.

-// Memory Allocator functions. Use SetAllocatorFunctions() to change them.

-    // Tables
-    // - Full-featured replacement for old Columns API.
-    // - See Demo->Tables for demo code.
-    // - See top of imgui_tables.cpp for general commentary.
-    // - See ImGuiTableFlags_ and ImGuiTableColumnFlags_ enums for a description of available flags.
-    // The typical call flow is:
-    // - 1. Call BeginTable().
-    // - 2. Optionally call TableSetupColumn() to submit column name/flags/defaults.
-    // - 3. Optionally call TableSetupScrollFreeze() to request scroll freezing of columns/rows.
-    // - 4. Optionally call TableHeadersRow() to submit a header row. Names are pulled from TableSetupColumn() data.
-    // - 5. Populate contents:
-    //    - In most situations you can use TableNextRow() + TableSetColumnIndex(N) to start appending into a column.
-    //    - If you are using tables as a sort of grid, where every columns is holding the same type of contents,
-    //      you may prefer using TableNextColumn() instead of TableNextRow() + TableSetColumnIndex().
-    //      TableNextColumn() will automatically wrap-around into the next row if needed.
-    //    - IMPORTANT: Comparatively to the old Columns() API, we need to call TableNextColumn() for the first column!
-    //    - Summary of possible call flow:
-    //        --------------------------------------------------------------------------------------------------------
-    //        TableNextRow() -> TableSetColumnIndex(0) -> Text("Hello 0") -> TableSetColumnIndex(1) -> Text("Hello 1")  // OK
-    //        TableNextRow() -> TableNextColumn()      -> Text("Hello 0") -> TableNextColumn()      -> Text("Hello 1")  // OK
-    //                          TableNextColumn()      -> Text("Hello 0") -> TableNextColumn()      -> Text("Hello 1")  // OK: TableNextColumn() automatically gets to next row!
-    //        TableNextRow()                           -> Text("Hello 0")                                               // Not OK! Missing TableSetColumnIndex() or TableNextColumn()! Text will not appear!

-// - Important! Sizing policies have complex and subtle side effects, much more so than you would expect.
-//   Read comments/demos carefully + experiment with live demos to get acquainted with them.
-// - The DEFAULT sizing policies are:
-//    - Default to ImGuiTableFlags_SizingFixedFit    if ScrollX is on, or if host window has ImGuiWindowFlags_AlwaysAutoResize.
-//    - Default to ImGuiTableFlags_SizingStretchSame if ScrollX is off.
-// - When ScrollX is off:
-//    - Table defaults to ImGuiTableFlags_SizingStretchSame -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch with same weight.
-//    - Columns sizing policy allowed: Stretch (default), Fixed/Auto.
-//    - Fixed Columns (if any) will generally obtain their requested width (unless the table cannot fit them all).
-//    - Stretch Columns will share the remaining width according to their respective weight.
-//    - Mixed Fixed/Stretch columns is possible but has various side-effects on resizing behaviors.
-//      The typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
-//      (this is because the visible order of columns have subtle but necessary effects on how they react to manual resizing).
-// - When ScrollX is on:
-//    - Table defaults to ImGuiTableFlags_SizingFixedFit -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed
-//    - Columns sizing policy allowed: Fixed/Auto mostly.
-//    - Fixed Columns can be enlarged as needed. Table will show an horizontal scrollbar if needed.
-//    - When using auto-resizing (non-resizable) fixed columns, querying the content width to use item right-alignment e.g. SetNextItemWidth(-FLT_MIN) doesn't make sense, would create a feedback loop.
-//    - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
-//      If you specify a value for 'inner_width' then effectively the scrolling space is known and Stretch or mixed Fixed/Stretch columns become meaningful again.
-// - Read on documentation at the top of imgui_tables.cpp for details.

-// - You generally do NOT need to care or use this ever. But we need to make it available in imgui.h because some of our public structures are relying on it.
-// - We use std-like naming convention here, which is a little unusual for this codebase.

-// - Important: our implementation does NOT call C++ constructors/destructors, we treat everything as raw data! This is intentional but be extra mindful of that,
-//   Do NOT use this class as a std::vector replacement in your own code! Many of the structures used by dear imgui can be safely initialized by a zero-memset.

-// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
-//   You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
-// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
-// - This is an old API and it is currently awkward for those and and various other reasons! We will address them in the future!

-// dear imgui: Platform Backend for GLFW
-// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
-// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
-// (Requires: GLFW 3.1+)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
-// Read online: https://github.com/ocornut/imgui/tree/master/docs
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after iniitializing backend.
-//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago)with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-//  2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
-//  2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
-//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-//  2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
-//  2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
-//  2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
-//  2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
-//  2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
-//  2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-//  2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
-//  2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
-//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-//  2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
-//  2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
-//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-//  2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
-//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-//  2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
-//  2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-//  2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
-//  2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
-//  2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

-// dear imgui: Platform Backend for GLFW
-// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
-// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
-// Read online: https://github.com/ocornut/imgui/tree/master/docs
-
-// About GLSL version:
-// The 'glsl_version' initialization parameter defaults to "#version 150" if NULL.
-// Only override if your GL version doesn't handle this GLSL version. Keep NULL if unsure!

-// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-//  [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
-// Read online: https://github.com/ocornut/imgui/tree/master/docs
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2021-12-15: OpenGL: Using buffer orphaning + glBufferSubData(), seems to fix leaks with multi-viewports with some Intel HD drivers.

-//  2021-08-19: OpenGL: Embed and use our own minimal GL loader (imgui_impl_opengl3_loader.h), removing requirement and support for third-party loader.
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).

-//  2020-10-23: OpenGL: Backup, setup and restore GL_PRIMITIVE_RESTART state.
-//  2020-10-15: OpenGL: Use glGetString(GL_VERSION) instead of glGetIntegerv(GL_MAJOR_VERSION, ...) when the later returns zero (e.g. Desktop GL 2.x)
-//  2020-09-17: OpenGL: Fix to avoid compiling/calling glBindSampler() on ES or pre 3.3 context which have the defines set by a loader.
-//  2020-07-10: OpenGL: Added support for glad2 OpenGL loader.

-//  2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
-//  2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.

-//  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
-//  2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).

-//  2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer.
-//  2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150".
-//  2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
-//  2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.

-// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-//  [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
-// Read online: https://github.com/ocornut/imgui/tree/master/docs
-
-// About GLSL version:
-//  The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
-//  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
-//  Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

-// Typical tables call flow: (root level is generally public API):
-//-----------------------------------------------------------------------------
-// - BeginTable()                               user begin into a table
-//    | BeginChild()                            - (if ScrollX/ScrollY is set)
-//    | TableBeginInitMemory()                  - first time table is used
-//    | TableResetSettings()                    - on settings reset
-//    | TableLoadSettings()                     - on settings load
-//    | TableBeginApplyRequests()               - apply queued resizing/reordering/hiding requests
-//    | - TableSetColumnWidth()                 - apply resizing width (for mouse resize, often requested by previous frame)
-//    |    - TableUpdateColumnsWeightFromWidth()- recompute columns weights (of stretch columns) from their respective width
-// - TableSetupColumn()                         user submit columns details (optional)

-//-----------------------------------------------------------------------------
-// - TableUpdateLayout() [Internal]             followup to BeginTable(): setup everything: widths, columns positions, clipping rectangles. Automatically called by the FIRST call to TableNextRow() or TableHeadersRow().
-//    | TableSetupDrawChannels()                - setup ImDrawList channels
-//    | TableUpdateBorders()                    - detect hovering columns for resize, ahead of contents submission
-//    | TableDrawContextMenu()                  - draw right-click context menu
-//-----------------------------------------------------------------------------
-// - TableHeadersRow() or TableHeader()         user submit a headers row (optional)
-//    | TableSortSpecsClickColumn()             - when left-clicked: alter sort order and sort direction
-//    | TableOpenContextMenu()                  - when right-clicked: trigger opening of the default context menu
-// - TableGetSortSpecs()                        user queries updated sort specs (optional, generally after submitting headers)
-// - TableNextRow()                             user begin into a new row (also automatically called by TableHeadersRow())
-//    | TableEndRow()                           - finish existing row
-//    | TableBeginRow()                         - add a new row
-// - TableSetColumnIndex() / TableNextColumn()  user begin into a cell
-//    | TableEndCell()                          - close existing column/cell
-//    | TableBeginCell()                        - enter into current column/cell
-// - [...]                                      user emit contents
-//-----------------------------------------------------------------------------
-// - EndTable()                                 user ends the table
-//    | TableDrawBorders()                      - draw outer borders, inner vertical borders
-//    | TableMergeDrawChannels()                - merge draw channels if clipping isn't required

-// TABLE SIZING
-//-----------------------------------------------------------------------------
-// (Read carefully because this is subtle but it does make sense!)
-//-----------------------------------------------------------------------------
-// About 'outer_size':
-// Its meaning needs to differ slightly depending on if we are using ScrollX/ScrollY flags.
-// Default value is ImVec2(0.0f, 0.0f).
-//   X
-//   - outer_size.x <= 0.0f  ->  Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge.
-//   - outer_size.x  > 0.0f  ->  Set Fixed width.
-//   Y with ScrollX/ScrollY disabled: we output table directly in current window
-//   - outer_size.y  < 0.0f  ->  Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful is parent window can vertically scroll.
-//   - outer_size.y  = 0.0f  ->  No minimum height (but will auto extend, unless _NoHostExtendY is set)
-//   - outer_size.y  > 0.0f  ->  Set Minimum height (but will auto extend, unless _NoHostExtenY is set)
-//   Y with ScrollX/ScrollY enabled: using a child window for scrolling
-//   - outer_size.y  < 0.0f  ->  Bottom-align. Not meaningful is parent window can vertically scroll.
-//   - outer_size.y  = 0.0f  ->  Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window.
-//   - outer_size.y  > 0.0f  ->  Set Exact height. Recommended when using Scrolling on any axis.
-//-----------------------------------------------------------------------------
-// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.
-// Important to that note how the two flags have slightly different behaviors!
-//   - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used.
-//   - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible.
-// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height.
-// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not easily noticeable)
-//-----------------------------------------------------------------------------
-// About 'inner_width':
-//   With ScrollX disabled:
-//   - inner_width          ->  *ignored*
-//   With ScrollX enabled:
-//   - inner_width  < 0.0f  ->  *illegal* fit in known width (right align from outer_size.x) <-- weird
-//   - inner_width  = 0.0f  ->  fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns.
-//   - inner_width  > 0.0f  ->  override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space!
-//-----------------------------------------------------------------------------
-// Details:
-// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept
-//   of "available space" doesn't make sense.
-// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding
-//   of what the value does.
-//-----------------------------------------------------------------------------
-
-//-----------------------------------------------------------------------------
-// COLUMNS SIZING POLICIES
-//-----------------------------------------------------------------------------
-// About overriding column sizing policy and width/weight with TableSetupColumn():
-// We use a default parameter of 'init_width_or_weight == -1'.
-//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  <= 0 (default)  --> width is automatic
-//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  >  0 (explicit) --> width is custom
-//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight <= 0 (default)  --> weight is 1.0f
-//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight >  0 (explicit) --> weight is custom
-// Widths are specified _without_ CellPadding. If you specify a width of 100.0f, the column will be cover (100.0f + Padding * 2.0f)
-// and you can fit a 100.0f wide item in it without clipping and with full padding.
-//-----------------------------------------------------------------------------
-// About default sizing policy (if you don't specify a ImGuiTableColumnFlags_WidthXXXX flag)
-//   - with Table policy ImGuiTableFlags_SizingFixedFit      --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is equal to contents width
-//   - with Table policy ImGuiTableFlags_SizingFixedSame     --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is max of all contents width
-//   - with Table policy ImGuiTableFlags_SizingStretchSame   --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is 1.0f
-//   - with Table policy ImGuiTableFlags_SizingStretchWeight --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is proportional to contents
-// Default Width and default Weight can be overridden when calling TableSetupColumn().
-//-----------------------------------------------------------------------------
-// About mixing Fixed/Auto and Stretch columns together:
-//   - the typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
-//   - using mixed policies with ScrollX does not make much sense, as using Stretch columns with ScrollX does not make much sense in the first place!
-//     that is, unless 'inner_width' is passed to BeginTable() to explicitly provide a total width to layout columns in.
-//   - when using ImGuiTableFlags_SizingFixedSame with mixed columns, only the Fixed/Auto columns will match their widths to the width of the maximum contents.
-//   - when using ImGuiTableFlags_SizingStretchSame with mixed columns, only the Stretch columns will match their weight/widths.
-//-----------------------------------------------------------------------------
-// About using column width:
-// If a column is manual resizable or has a width specified with TableSetupColumn():
-//   - you may use GetContentRegionAvail().x to query the width available in a given column.
-//   - right-side alignment features such as SetNextItemWidth(-x) or PushItemWidth(-x) will rely on this width.
-// If the column is not resizable and has no width specified with TableSetupColumn():
-//   - its width will be automatic and be set to the max of items submitted.
-//   - therefore you generally cannot have ALL items of the columns use e.g. SetNextItemWidth(-FLT_MIN).
-//   - but if the column has one or more items of known/fixed size, this will become the reference width used by SetNextItemWidth(-FLT_MIN).
-//-----------------------------------------------------------------------------
-
-
-//-----------------------------------------------------------------------------
-// TABLES CLIPPING/CULLING
-//-----------------------------------------------------------------------------
-// About clipping/culling of Rows in Tables:
-// - For large numbers of rows, it is recommended you use ImGuiListClipper to only submit visible rows.
-//   ImGuiListClipper is reliant on the fact that rows are of equal height.
-//   See 'Demo->Tables->Vertical Scrolling' or 'Demo->Tables->Advanced' for a demo of using the clipper.
-// - Note that auto-resizing columns don't play well with using the clipper.
-//   By default a table with _ScrollX but without _Resizable will have column auto-resize.
-//   So, if you want to use the clipper, make sure to either enable _Resizable, either setup columns width explicitly with _WidthFixed.
-//-----------------------------------------------------------------------------
-// About clipping/culling of Columns in Tables:
-// - Both TableSetColumnIndex() and TableNextColumn() return true when the column is visible or performing
-//   width measurements. Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know
-//   it is not going to contribute to row height.
-//   In many situations, you may skip submitting contents for every column but one (e.g. the first one).
-// - Case A: column is not hidden by user, and at least partially in sight (most common case).
-// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output.
-// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.).
-//
-//                        [A]         [B]          [C]
-//  TableNextColumn():    true        false        false       -> [userland] when TableNextColumn() / TableSetColumnIndex() return false, user can skip submitting items but only if the column doesn't contribute to row height.
-//          SkipItems:    false       false        true        -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output.
-//           ClipRect:    normal      zero-width   zero-width  -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way.
-//  ImDrawList output:    normal      dummy        dummy       -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway).
-//
-// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row.
-//   However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer.
-//-----------------------------------------------------------------------------
-// About clipping/culling of whole Tables:
-// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false.

-// This function reorder draw channels based on matching clip rectangle, to facilitate merging them. Called by EndTable().
-// For simplicity we call it TableMergeDrawChannels() but in fact it only reorder channels + overwrite ClipRect,
-// actual merging is done by table->DrawSplitter.Merge() which is called right after TableMergeDrawChannels().
-//
-// Columns where the contents didn't stray off their local clip rectangle can be merged. To achieve
-// this we merge their clip rect and make them contiguous in the channel list, so they can be merged
-// by the call to DrawSplitter.Merge() following to the call to this function.
-// We reorder draw commands by arranging them into a maximum of 4 distinct groups:
-//
-//   1 group:               2 groups:              2 groups:              4 groups:
-//   [ 0. ] no freeze       [ 0. ] row freeze      [ 01 ] col freeze      [ 01 ] row+col freeze
-//   [ .. ]  or no scroll   [ 2. ]  and v-scroll   [ .. ]  and h-scroll   [ 23 ]  and v+h-scroll
-//
-// Each column itself can use 1 channel (row freeze disabled) or 2 channels (row freeze enabled).
-// When the contents of a column didn't stray off its limit, we move its channels into the corresponding group
-// based on its position (within frozen rows/columns groups or not).
-// At the end of the operation our 1-4 groups will each have a ImDrawCmd using the same ClipRect.
-// This function assume that each column are pointing to a distinct draw channel,
-// otherwise merge_group->ChannelsCount will not match set bit count of merge_group->ChannelsMask.
-//
-// Column channels will not be merged into one of the 1-4 groups in the following cases:
-// - The contents stray off its clipping rectangle (we only compare the MaxX value, not the MinX value).
-//   Direct ImDrawList calls won't be taken into account by default, if you use them make sure the ImGui:: bounds
-//   matches, by e.g. calling SetCursorScreenPos().
-// - The channel uses more than one draw command itself. We drop all our attempt at merging stuff here..
-//   we could do better but it's going to be rare and probably not worth the hassle.
-// Columns for which the draw channel(s) haven't been merged with other will use their own ImDrawCmd.
-//

-// [DEAR IMGUI]
-// This is a slightly modified version of stb_rect_pack.h 1.00.
-// Those changes would need to be pushed into nothings/stb:
-// - Added STBRP__CDECL
-// Grep for [DEAR IMGUI] to find the changes.
-
-// stb_rect_pack.h - v1.00 - public domain - rectangle packing
-// Sean Barrett 2014
-//
-// Useful for e.g. packing rectangular textures into an atlas.
-// Does not do rotation.
-//
-// Not necessarily the awesomest packing method, but better than
-// the totally naive one in stb_truetype (which is primarily what
-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please
-// implement them to the same API, but with a different init
-// function.

-// [DEAR IMGUI]
-// This is a slightly modified version of stb_textedit.h 1.13.
-// Those changes would need to be pushed into nothings/stb:
-// - Fix in stb_textedit_discard_redo (see https://github.com/nothings/stb/issues/321)
-// Grep for [DEAR IMGUI] to find the changes.
-
-// stb_textedit.h - v1.13  - public domain - Sean Barrett
-// Development of this library was sponsored by RAD Game Tools
-//
-// This C header file implements the guts of a multi-line text-editing
-// widget; you implement display, word-wrapping, and low-level string
-// insertion/deletion, and stb_textedit will map user inputs into
-// insertions & deletions, plus updates to the cursor position,
-// selection state, and undo state.
-//
-// It is intended for use in games and other systems that need to build
-// their own custom widgets and which do not have heavy text-editing
-// requirements (this library is not recommended for use for editing large
-// texts, as its performance does not scale and it has limited undo).
-//
-// Non-trivial behaviors are modelled after Windows text controls.
-//
-//
-// LICENSE
-//

-//
-// DEPENDENCIES

-// Uses the C runtime function 'memmove', which you can override
-// by defining STB_TEXTEDIT_memmove before the implementation.

-//
-// USAGE
-//
-// This file behaves differently depending on what symbols you define
-// before including it.
-//
-//
-// Header-file mode:
-//
-//   If you do not define STB_TEXTEDIT_IMPLEMENTATION before including this,
-//   it will operate in "header file" mode. In this mode, it declares a
-//   single public symbol, STB_TexteditState, which encapsulates the current
-//   state of a text widget (except for the string, which you will store
-//   separately).
-//
-//   To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
-//   primitive type that defines a single character (e.g. char, wchar_t, etc).
-//
-//   To save space or increase undo-ability, you can optionally define the
-//   following things that are used by the undo system:
-//
-//      STB_TEXTEDIT_POSITIONTYPE         small int type encoding a valid cursor position
-//      STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//      STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-//   If you don't define these, they are set to permissive types and
-//   moderate sizes. The undo system does no memory allocations, so
-//   it grows STB_TexteditState by the worst-case storage which is (in bytes):
-//
-//        [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT
-//      +          sizeof(STB_TEXTEDIT_CHARTYPE)      * STB_TEXTEDIT_UNDOCHAR_COUNT
-//
-//
-// Implementation mode:
-//
-//   If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
-//   will compile the implementation of the text edit widget, depending
-//   on a large number of symbols which must be defined before the include.
-//
-//   The implementation is defined only as static functions. You will then
-//   need to provide your own APIs in the same file which will access the
-//   static functions.
-//
-//   The basic concept is that you provide a "string" object which
-//   behaves like an array of characters. stb_textedit uses indices to
-//   refer to positions in the string, implicitly representing positions
-//   in the displayed textedit. This is true for both plain text and
-//   rich text; even with rich text stb_truetype interacts with your
-//   code as if there was an array of all the displayed characters.
-//
-// Symbols that must be the same in header-file and implementation mode:
-//
-//     STB_TEXTEDIT_CHARTYPE             the character type
-//     STB_TEXTEDIT_POSITIONTYPE         small type that is a valid cursor position
-//     STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//     STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-// Symbols you must define for implementation mode:
-//
-//    STB_TEXTEDIT_STRING               the type of object representing a string being edited,
-//                                      typically this is a wrapper object with other data you need
-//
-//    STB_TEXTEDIT_STRINGLEN(obj)       the length of the string (ideally O(1))
-//    STB_TEXTEDIT_LAYOUTROW(&r,obj,n)  returns the results of laying out a line of characters
-//                                        starting from character #n (see discussion below)
-//    STB_TEXTEDIT_GETWIDTH(obj,n,i)    returns the pixel delta from the xpos of the i'th character
-//                                        to the xpos of the i+1'th char for a line of characters
-//                                        starting at character #n (i.e. accounts for kerning
-//                                        with previous char)
-//    STB_TEXTEDIT_KEYTOTEXT(k)         maps a keyboard input to an insertable character
-//                                        (return type is int, -1 means not valid to insert)
-//    STB_TEXTEDIT_GETCHAR(obj,i)       returns the i'th character of obj, 0-based
-//    STB_TEXTEDIT_NEWLINE              the character returned by _GETCHAR() we recognize
-//                                        as manually wordwrapping for end-of-line positioning
-//
-//    STB_TEXTEDIT_DELETECHARS(obj,i,n)      delete n characters starting at i
-//    STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n)   insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
-//
-//    STB_TEXTEDIT_K_SHIFT       a power of two that is or'd in to a keyboard input to represent the shift key
-//
-//    STB_TEXTEDIT_K_LEFT        keyboard input to move cursor left
-//    STB_TEXTEDIT_K_RIGHT       keyboard input to move cursor right
-//    STB_TEXTEDIT_K_UP          keyboard input to move cursor up
-//    STB_TEXTEDIT_K_DOWN        keyboard input to move cursor down
-//    STB_TEXTEDIT_K_PGUP        keyboard input to move cursor up a page
-//    STB_TEXTEDIT_K_PGDOWN      keyboard input to move cursor down a page
-//    STB_TEXTEDIT_K_LINESTART   keyboard input to move cursor to start of line  // e.g. HOME
-//    STB_TEXTEDIT_K_LINEEND     keyboard input to move cursor to end of line    // e.g. END
-//    STB_TEXTEDIT_K_TEXTSTART   keyboard input to move cursor to start of text  // e.g. ctrl-HOME
-//    STB_TEXTEDIT_K_TEXTEND     keyboard input to move cursor to end of text    // e.g. ctrl-END
-//    STB_TEXTEDIT_K_DELETE      keyboard input to delete selection or character under cursor
-//    STB_TEXTEDIT_K_BACKSPACE   keyboard input to delete selection or character left of cursor
-//    STB_TEXTEDIT_K_UNDO        keyboard input to perform undo
-//    STB_TEXTEDIT_K_REDO        keyboard input to perform redo
-//
-// Optional:
-//    STB_TEXTEDIT_K_INSERT              keyboard input to toggle insert mode
-//    STB_TEXTEDIT_IS_SPACE(ch)          true if character is whitespace (e.g. 'isspace'),
-//                                          required for default WORDLEFT/WORDRIGHT handlers
-//    STB_TEXTEDIT_MOVEWORDLEFT(obj,i)   custom handler for WORDLEFT, returns index to move cursor to
-//    STB_TEXTEDIT_MOVEWORDRIGHT(obj,i)  custom handler for WORDRIGHT, returns index to move cursor to
-//    STB_TEXTEDIT_K_WORDLEFT            keyboard input to move cursor left one word // e.g. ctrl-LEFT
-//    STB_TEXTEDIT_K_WORDRIGHT           keyboard input to move cursor right one word // e.g. ctrl-RIGHT
-//    STB_TEXTEDIT_K_LINESTART2          secondary keyboard input to move cursor to start of line
-//    STB_TEXTEDIT_K_LINEEND2            secondary keyboard input to move cursor to end of line
-//    STB_TEXTEDIT_K_TEXTSTART2          secondary keyboard input to move cursor to start of text
-//    STB_TEXTEDIT_K_TEXTEND2            secondary keyboard input to move cursor to end of text
-//
-// Keyboard input must be encoded as a single integer value; e.g. a character code
-// and some bitflags that represent shift states. to simplify the interface, SHIFT must
-// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
-// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
-//
-// You can encode other things, such as CONTROL or ALT, in additional bits, and
-// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
-// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
-// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
-// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
-// API below. The control keys will only match WM_KEYDOWN events because of the
-// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
-// bit so it only decodes WM_CHAR events.
-//
-// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
-// row of characters assuming they start on the i'th character--the width and
-// the height and the number of characters consumed. This allows this library
-// to traverse the entire layout incrementally. You need to compute word-wrapping
-// here.
-//
-// Each textfield keeps its own insert mode state, which is not how normal
-// applications work. To keep an app-wide insert mode, update/copy the
-// "insert_mode" field of STB_TexteditState before/after calling API functions.
-//
-// API

-//          be relative to the text widget, with (0,0) being the top left.
-//
-//      drag:
-//          call this with the mouse x,y on a mouse drag/up; it will update the
-//          cursor and the selection end point
-//
-//      cut:
-//          call this to delete the current selection; returns true if there was

-//      key:
-//          call this for keyboard inputs sent to the textfield. you can use it
-//          for "key down" events or for "translated" key events. if you need to
-//          do both (as in Win32), or distinguish Unicode characters from control
-//          inputs, set a high bit to distinguish the two; then you can define the
-//          various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
-//          set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
-//          clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to
-//          anything other type you wante before including.
-//
-//
-//   When rendering, you can read the cursor position and selection state from
-//   the STB_TexteditState.
-//
-//
-// Notes:
-//
-// This is designed to be usable in IMGUI, so it allows for the possibility of
-// running in an IMGUI that has NOT cached the multi-line layout. For this
-// reason, it provides an interface that is compatible with computing the
-// layout incrementally--we try to make sure we make as few passes through
-// as possible. (For example, to locate the mouse pointer in the text, we
-// could define functions that return the X and Y positions of characters
-// and binary search Y and then X, but if we're doing dynamic layout this
-// will run the layout algorithm many times, so instead we manually search
-// forward in one pass. Similar logic applies to e.g. up-arrow and
-// down-arrow movement.)
-//
-// If it's run in a widget that *has* cached the layout, then this is less
-// efficient, but it's not horrible on modern computers. But you wouldn't
-// want to edit million-line files with it.

-//   Starting with version 1.06, the rasterizer was replaced with a new,
-//   faster and generally-more-precise rasterizer. The new rasterizer more
-//   accurately measures pixel coverage for anti-aliasing, except in the case
-//   where multiple shapes overlap, in which case it overestimates the AA pixel
-//   coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
-//   this turns out to be a problem, you can re-enable the old rasterizer with
-//        #define STBTT_RASTERIZER_VERSION 1
-//   which will incur about a 15% speed hit.
-//
-// ADDITIONAL DOCUMENTATION
-//
-//   Immediately after this block comment are a series of sample programs.
-//
-//   After the sample programs is the "header file" section. This section
-//   includes documentation for each API function.
-//
-//   Some important concepts to understand to use this library:
-//
-//      Codepoint
-//         Characters are defined by unicode codepoints, e.g. 65 is
-//         uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
-//         the hiragana for "ma".
-//
-//      Glyph
-//         A visual character shape (every codepoint is rendered as
-//         some glyph)
-//
-//      Glyph index
-//         A font-specific integer ID representing a glyph
-//
-//      Baseline
-//         Glyph shapes are defined relative to a baseline, which is the
-//         bottom of uppercase characters. Characters extend both above
-//         and below the baseline.
-//
-//      Current Point
-//         As you draw text to the screen, you keep track of a "current point"
-//         which is the origin of each character. The current point's vertical
-//         position is the baseline. Even "baked fonts" use this model.
-//
-//      Vertical Font Metrics
-//         The vertical qualities of the font, used to vertically position
-//         and space the characters. See docs for stbtt_GetFontVMetrics.
-//
-//      Font Size in Pixels or Points
-//         The preferred interface for specifying font sizes in stb_truetype
-//         is to specify how tall the font's vertical extent should be in pixels.
-//         If that sounds good enough, skip the next paragraph.
-//
-//         Most font APIs instead use "points", which are a common typographic
-//         measurement for describing font size, defined as 72 points per inch.
-//         stb_truetype provides a point API for compatibility. However, true
-//         "per inch" conventions don't make much sense on computer displays
-//         since different monitors have different number of pixels per
-//         inch. For example, Windows traditionally uses a convention that
-//         there are 96 pixels per inch, thus making 'inch' measurements have
-//         nothing to do with inches, and thus effectively defining a point to
-//         be 1.333 pixels. Additionally, the TrueType font data provides
-//         an explicit scale factor to scale a given font's glyphs to points,
-//         but the author has observed that this scale factor is often wrong
-//         for non-commercial fonts, thus making fonts scaled in points
-//         according to the TrueType spec incoherently sized in practice.
-//
-// DETAILED USAGE:
-//
-//  Scale:
-//    Select how high you want the font to be, in points or pixels.
-//    Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
-//    a scale factor SF that will be used by all other functions.
-//
-//  Baseline:
-//    You need to select a y-coordinate that is the baseline of where
-//    your text will appear. Call GetFontBoundingBox to get the baseline-relative
-//    bounding box for all characters. SF*-y0 will be the distance in pixels
-//    that the worst-case character could extend above the baseline, so if
-//    you want the top edge of characters to appear at the top of the
-//    screen where y=0, then you would set the baseline to SF*-y0.
-//
-//  Current point:
-//    Set the current point where the first character will appear. The
-//    first character could extend left of the current point; this is font
-//    dependent. You can either choose a current point that is the leftmost
-//    point and hope, or add some padding, or check the bounding box or
-//    left-side-bearing of the first character to be displayed and set
-//    the current point based on that.
-//
-//  Displaying a character:
-//    Compute the bounding box of the character. It will contain signed values
-//    relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
-//    then the character should be displayed in the rectangle from
-//    <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
-//
-//  Advancing for the next character:
-//    Call GlyphHMetrics, and compute 'current_point += SF * advance'.
-//
-//
-// ADVANCED USAGE
-//
-//   Quality:
-//
-//    - Use the functions with Subpixel at the end to allow your characters
-//      to have subpixel positioning. Since the font is anti-aliased, not
-//      hinted, this is very import for quality. (This is not possible with
-//      baked fonts.)
-//
-//    - Kerning is now supported, and if you're supporting subpixel rendering
-//      then kerning is worth using to give your text a polished look.
-//
-//   Performance:
-//
-//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
-//      if you don't do this, stb_truetype is forced to do the conversion on
-//      every call.
-//
-//    - There are a lot of memory allocations. We should modify it to take
-//      a temp buffer and allocate from the temp buffer (without freeing),
-//      should help performance a lot.
-//
-// NOTES
-//
-//   The system uses the raw data found in the .ttf file without changing it
-//   and without building auxiliary data structures. This is a bit inefficient
-//   on little-endian systems (the data is big-endian), but assuming you're
-//   caching the bitmaps or glyph shapes this shouldn't be a big deal.
-//
-//   It appears to be very hard to programmatically determine what font a
-//   given file is in a general way. I provide an API for this, but I don't
-//   recommend it.

-//        return value      --  a 2D array of bytes 0..255, width*height in size
-//
-// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
-// optimal use of the limited 0..255 for your application, trading off precision
-// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
-//
-// Example:
-//      scale = stbtt_ScaleForPixelHeight(22)
-//      padding = 5
-//      onedge_value = 180
-//      pixel_dist_scale = 180/5.0 = 36.0
-//
-//      This will create an SDF bitmap in which the character is about 22 pixels
-//      high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
-//      shape, sample the SDF at each pixel and fill the pixel if the SDF value
-//      is greater than or equal to 180/255. (You'll actually want to antialias,
-//      which is beyond the scope of this example.) Additionally, you can compute
-//      offset outlines (e.g. to stroke the character border inside & outside,
-//      or only outside). For example, to fill outside the character up to 3 SDF
-//      pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
-//      choice of variables maps a range from 5 pixels outside the shape to
-//      2 pixels inside the shape to 0..255; this is intended primarily for apply
-//      outside effects only (the interior range is needed to allow proper
-//      antialiasing of the font at *smaller* sizes)
-//
-// The function computes the SDF analytically at each SDF pixel, not by e.g.
-// building a higher-res bitmap and approximating it. In theory the quality
-// should be as high as possible for an SDF of this size & representation, but
-// unclear if this is true in practice (perhaps building a higher-res bitmap
-// and computing from that can allow drop-out prevention).
-//
-// The algorithm has not been optimized at all, so expect it to be slow
-// if computing lots of characters or very large sizes.
