kichikuou 49cf5d55ed Refactor CG loaders 
Now they return a newly introduced CG object instead of writing directly
to VRAM. The palette is still written directly in the load functions.

kichikuou 33418f8cb5 AGS: Make VRAM 8 bits per pixel 
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.

kichikuou a13719d84c AGS: Fix a bug in GAIJI.DAT loading code 
There was a bug in the JIS to Shift_JIS conversion code, causing out-of-
range access to the gaiji array. Since the conversion was not necessary
in the first place, the indexes to the array are now calculated directly
from JIS code points.

kichikuou 7f6a085f56 Scanline screen effect 
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.

kichikuou ec1dfbffcf Use non-square pixels for Gakuen Senki 
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.

kichikuou dc471399e5 Rewrite fade in / fade out implementation 
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.

kichikuou 98038a5c74 Do not use SDL_RWFromFile on Windows

Mingw-w64's SDL2 package).

Fixes #11.
