Provide a trackpad-style on-screen cursor for touch environments (mainly
Android), where touching the screen previously jumped the pointer to the
touched location (absolute) and SDL hardware cursors are invisible.
When enabled, a finger drag moves an arrow cursor relatively, a tap
left-clicks (held briefly so polling games detect it), two fingers
right-click, and a stationary long press starts a left-button drag. Real
mouse motion is ignored (including the spurious startup (0,0) event), and
program-driven cursor moves are followed via the internal pointer location
instead of warping the OS cursor.
The feature is disabled by default and enabled via the -virtualpointer
command-line option, the virtualpointer profile setting, or the "Virtual
mouse pointer" toggle in the Android launcher (persisted in
SharedPreferences and passed to the engine as -virtualpointer).
The gesture handling lives in event.c and the cursor rendering in the new
platform-independent virtual_pointer module, so it works on any touch
target.

Switch the bundled mincho font from a Source Han Serif JP subset to a
subset of IPA Mincho, which has monospace ASCII glyphs.
IPA Mincho's hhea ascent/descent already match its OS/2 typo metrics, so
adjust_metrics.py is no longer needed. However, IPA Mincho is distributed
under the IPA Font License v1.0, under which a subset is a "Derived
Program"; Article 3.1(4) forbids the derived font's name from containing
the licensed program's name ("IPA"). Add rename_font.py to rewrite the
name table accordingly, and replace licenses/mincho.txt with the IPA Font
License.
Graymerca uses JPEG images for map tiles, which suffers from color
bleeding due to chroma upsampling in the JPEG decoder.
Since stb_image cannot disable the bilinear upsampling filter, this
switches the JPEG decoder to NanoJPEG.
Fixes#67.
Launcher.kt extracts given ZIP file to the internal storage, preserving
its directory structure.
Before this change, if the game files were in a subdirectory, an
xsystem35.gr file was generated containing the path to the game files.
However, with this method, .xsys35rc and some data files (such as map
files of Kaeru Nyo) could not be loaded.
After this change, Launcher.kt will no longer generate the xsystem35.gr
file. Instead, it records the directory where the game is located in
game_directory.txt, and specify that directory in -gamedir to launch
xsystem35.
Fixes#51.
Before this, line k of the playlist file corresponded to track k-1 on
Android. After this, line k corresponds to track k, which is consistent
with other platforms.
Playlists generated in previous versions of xsystem35-sdl2 will be
automatically converted.
The title.txt file is written when the MT command is used, however some
games (Daiakuji, AmbivalenZ, Ikenai Katsumi sensei) does not use the MT
command. As a result, these titles did not appear in the launcher.
This makes the launcher use the name of the ZIP archive when the game
was installed as the alternate item name if the MT command was not used.
This allows installation from some ZIPs distributed by AliceSoft
archives, in Android < 7.0.
Some other ZIPs have game files with SJIS names, so change the error
message depending on whether there's a decode error.
The installer writes xsystem35.gr file into the game root directory.
Now save files are created at `files/save` directory, which is outside
the game directory. This scheme is the same as Kichikuou on Web, so it
would make transferring save data between two easier.
