1. ROM updated to 1.03.
2. Re-apply more fixes that were missed during the restructuring to be on par with PCem's speed.
3. Implemented Command DMA bus mastering required by Diamond Stealth 3D specific drivers (especially the GX2-based 4000).
4. Some indentation fixes.
1. TVP3026: disable lut mapping on 24bpp modes (mainly the S3 Vision968 drivers which use the TVP3026 ramdac).
2. S3 Vision968 (MiroVideo 40SV Ergo): Corrected 1280x1024 24bpp resolution.
3. ViRGE class: limit the FIFO entries in the bitblt regs to less than 16 entries and make the Image Transfers FIFO writes wraparound to 1 and reads to 0 (to allow at least a read to a write in the thread without hanging the entire emulator). Fixes Win3.1 PBRUSH colors while keeping performance on par with PCem.
SVGA: Added an indicator of the internal line to make matters easier for some vertical resolution problems.
TGUI 9400CXi: Fixed the basic acceleration as much as I could.
TGUI 9440AGi+: As with the line indicator, make matters easier for some resolution problems plus some refactoring of the bpp. Added write protection to some regs based on some documentation on the vt8601.
TGUI cursor: fixed the left edge of the cursor X offset.
S3: Apply the vblankstart = dispend statement only on enhanced modes, fixes vertical display on The Incredible Machine for DOS.
Commented out some excess logs.
Cleaned up the code and fixed the reset and LFB accesses. NT 4.0 now works with its v2.47 drivers without a soft reset (it used to only with a soft reset originally and, without it, hang with a blank screen upon reaching the GUI).
IBM 8514/A set:
Fixed a one off video bug that was causing the VGA video to not be restored after quitting a 8514/A GUI session (namely on Win2.x' 8514/A's driver).
ATI Mach32:
Fixed another vertical display issue when activated (in 1280x1024 mode, when 1024 was 1022).
All involved:
Apply RG's changedvram fix to 8514/A, Mach8/32 and XGA's changedvram pointers.
1. Ported the S3 ViRGE reset fix to the Pre-ViRGE cards.
2. Slight cleanup on the acceleration and logs.
3. Unused sequencer register data now return 0xff instead of 0. This fixes Scorched Earth 1.x on DOS using S3 Trio32/64/V+/V2/868/968 cards (on other S3 it works fine as is).
