Before this, the virtual VRAM was 32 bits per pixel, with each pixel
holding an 8-bit index color or 0x80RRGGBB. The latter was for Ayumi-
chan Monogatari Jisshaban, which has been unsupported since system3-sdl2
was forked from System3 for Win32.
This change removes the 0x80RRGGBB format and makes the virtual VRAM 8
bits per pixel.
It can be activated by the -scanline command line flag, system3.ini, or
the menubar on Windows. Effective especially for games with 200-line
screen mode, such as Little Vampire and Intruder.
Stretch 512 horizontal pixels to 582 pixels. This is the same pixel
aspect ratio used by WebMSX.
Also set SDL_HINT_RENDER_SCALE_QUALITY to "linear", to improve the
scaling quality.
Some screens in Alice's Cottage 3 have menus implemented on the script
side. The script does not know the absolute position of the mouse
pointer (cursor movement is done by obtaining the relative movement
distance of the mouse), so the mouse pointer and the selected item were
often misaligned, and the cursor could not be moved by touch operation.
This adds a hack to the K3 command that emulates cursor movements by
absolute mouse pointer location.
Before this change, fade in and fade out was implemented using a
16-steps dithering pattern.
Now fading uses alpha-blending. It behaves like the PC98 version, where
fading was done by palette animation.
This reduces `sizeof(AGS)` by 1.2MB.
- Added initial text / menu positions for newly-supported games
- convert_zenkaku and convert_hankaku are now public
- load_cg supports Ayumi Floppy
- VSP: A transparency value of 101 now ignores get_palette
FILEIO has been updated to resolve relative paths inside FILEIO::Fopen(),
which has been already done in System3-sdl2.
FILEIO::Fgets() now uses a length param.
Callsites for these functions are also updated to reduce the diff from
upstream.
