6b1d0b9e88 S3 mode fixes 2 and one small accel cleanup: 
1. Fixed 16bpp modes (including 15-bit) of the Trio32/64 that were doubling their horizontal resolution.
2. Made Bresenham Line easier to work with.

b7a4fa2a7c S3 refactoring: 
1. Made the 924 BIOS use the AT&T 491 ramdac since it supports such (tested).
2. Tweaks to the 928 Brooktree ID detection to make sure the cursor is shown correctly in 16bpp+ modes (it uses the BT485 ID detection so that it knows what BT is using to accommodate the cursor model).
3. Refactored the mode (CRTC50) and pitch timing stuff (moved to recalctimings for example) so that drivers/games/operating systems and what not can be used normally. (Warning, more stuff is to be tested due to a gazillion of combinations used by said stuff).
4. VRAM wraparound is now working as it should, fixes Commander Keen games.
5. Indentation fixes.
6. Attempt to fix 15/16bpp mode acceleration used by the 911/924 chips (not perfect and still has bugs).
7. Added the remaining missing stuff of the Sierra SC1502x RAMDAC including its 8BIT setting.
8. Some drivers use FIFO bits in non-FIFO configurations, should fix hang ups in some instances (namely the 928 S3 2.3 NT 3.1 drivers and possibly more).
9. Separated the 911/924 acceleration from the 80x/928+ one though the use of a function pointer.
10. Fixed the inverted colors in some instances using the S3 Trio64 driver in Win9x (mainly on soft reboots).
11. CX/CY (non-Blits) and DX/DY (Blits) wraparound correctly during their respective operations, fixes OS/2 software cursor once again while keeping existing stuff working.
12. Added some comments to keep track of some anomalies.
13. Fixed some badly formatted if's and switches.
14. Limited the SPEA Mercury Lite VRAM to 1MB per real world configurations.
