dd5c5f4a07 More ViRGE fixes (August 29th, 2024) 
Apparently the extended sequencer registers (>= 0x20) are required to have sane values on the STREAMS engine on GX2 and probably other chips in the ViRGE range.

47ee1c4ead Some fixes to the Streams engine of the ViRGE/Trio3D 
Make sure the ViRGE GX2 and up (including the Trio3D/2X) use the secondary stream only per what was found in the past.

aebaabb6b8 ViRGE changes of the day (August 20th, 2024) 
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.

a0d662e9c5 S3 changes (and TVP3026) of the day (August 15th, 2024) 
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.

* 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.
