1. Made the 4 color mode (67h) work properly now, including its 4 schemes on all ATI cards that support said mode.
2. Shadow set now has a true purpose for 8514/A compatibility on ATI Mach8/32.
3. Non-ATI 8514/A used to not work before because of the dev->local variable was not being set to 0 in the ibm8514_init() function, now it's fixed.
The current implementation still uses the shifter forced to Shift 256 mode to keep things generic, but we can always opt for a separate scanline renderer.
Seems the Tseng cards are as incompatible as the S3 cards in terms of pure IBM VGA emulation, especially the chain4 stuff, so accomodate the fix to the renderer. Fixes 8bpp rendering on Tseng cards when invoked.
This gives more likely behaviour when one loads more often than the address is incremented.
The behaviour matches an Intel GMA 4500MHD (2008) which is the earliest hardware I'm able to test right now.
It appears that the S3 Trio does something weird with its 8bpp modes.
Specifically, it seems to ignore some of the flags needed for dword mode.
I will keep looking into that and see if I can find a good solution.
Fixed ET4000/W32 (without letters) hardware cursor.
Fixed non-interlaced 1280x1024x8bpp Cirrus mode in the 5434.
Added a note regarding the Radius (HT209) 8bpp render.
Reworked the TGUI9440, but still WIP.
- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root
Unified screenshot code and moved it to video.c, it is now independent of both renderer and platform;
The EGA/(S)VGA overscan now also works for CGA, PCjr, Tandy, and CGA-using Amstrads;
Fixed EGA/(S)VGA overscan operation so it works correctly with scrolling and panning;
Fixed 320x200x32K and 320x200x64K modes on the ET4000/W32p;
Fixed the Video 7 1024i chip ID and video memory options, fixes#431;
Fixed a banking bug in the S3 cards, fixes Windows 9x and NeoPaint.
