* Fix duplicated logic in vid_svga.c
* Voodoo 3/Banshee emulation now has blanking extensions applied
* S3 ViRGE and Matrox video cards as well
* Tseng ET4000-series cards as well
* Fix off-by-one error in vid_cl54xx.c
Trident cards are yet to be investigated. XGA and 8514/A are yet to be made blanking extensions compliant. Mach64, Paradise/WDC and OAK OTI cards remain as-is for now.
Removed the threaded FIFO on the ViRGE cards due to bugs, instead, relying on a non-threaded FIFO again.
Fixed some 8MB parts of the blitter for the ViRGE/VX-based STB Velocity 3D card so that 8MB RAM detection doesn't glitch everything else, including the blitter.
- Renamed `cpp11_thread.cpp` to `thread.cpp`
- Removed features that are only supported by Win32 threads (`thread_wait` with timeout and mutex with spinlock)
- Fixed formatting in `thread.cpp`
Properly fixed text/graphics mode of the S3 pre-ViRGE cards.
PIX TRANS cleanups.
Added a sanity check to banking, per bit 0 of CRTC31.
Initial implementation of Enhanced 4-bit mode.
911/924 chips use CRTC43 bit 3 for enabling 15/16bpp mode.
fb_only variable used correctly as of now (depending if on 4bit or 8bit+ modes).
S3 ViRGE changes part 2:
Made the Trio3D/2X AGP use the PCI_ADD_AGP part accordingly
RAMDAC changes:
Sierra 11483 and 11487 don't have an RS2 signal so the four times reading scheme of 0x3c6 is used instead, per documentation.
Fixed AT&T 49x bpp selection.
Other changes:
Fixed remaining rendering issues with the Radius SVGA HT209 card.
Added a timer to improve perfomance of the 3D engine.
Made the Trio3D/2X available for all.
Reserved bit 2 of CR33 is now always set to make sure Win95's Trio3d/2X drivers work along with a workaround for the memory size.
Added preliminary DMA bus master capabilities.
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.
