S3 Pre-ViRGE changes of the day (September 26th, 2024)

Browse Source

1. Actually fix the remaining pinkish/reddish stuff in 32bpp modes properly (for real, especially OS/2 and possibly other stuff).
2. The Compare accel stuff is more sanitized.
3. When the BitBLT DY coordinates are negative, don't draw the pixels. This fixes some software cursor issues with OS/2's S3 3.03.xx drivers.
4. Reset the FIFO when the card is reset.
5. Indentation fixes (to be improved further however).
6. Implement bit 5 functionality of 0xBEE8 index 0xE (MULT_MISC) (and currently only in the Rectangle Fill command). This fixes missing text on I-O Data Vision968 specific drivers for Windows 3.10 Japanese (PC/AT compatible)
7. Moved the Streams engine out of the FIFO (like the ViRGE) as well as making all CRTC's of the Trio64V2 writable and SEQREGs from 0x10 onwards to make sure the Streams engine works properly.
8. Added a missing break from the RAMDAC read stuff.
9. Remove a leftover of PCem.
