6c933dd157 Voodoo: Implement missing AGP CMDFIFO features 
Note that the reproduction cases for command 6 currently appear to be a result of CMDFIFO corruption instead of actual usage.

71c9e69456 Mach32 changes of the day (February 20th, 2025) 
1. Actually fix the LFB access by subtracting the linear base address from the current address when LFB/MMIO is on. This fixes blankness of certain Mach32 drivers on Win3.1x.
2. Apply a minor but important fix to the fonts used by said Win3.1x driver when the dpconfig activates bit 2 without bit 12 set (e.g.: 0x2255), ergo, issuing host data as monochrome without swapping it.

b7100a6169 Video changes of the night (January 29th, 2025) 
Matrox MGA:
A break from work can save the day all so to say. Fixes bitblt'ing on WinNT4.0/Win2000 using 32bpp modes and possibly other stuff using said Matrox chip.

e61f3c8a5d Video changes of the day (January 26th, 2025) 
XGA:
1. Added a proper poll so to have its timings independent of the SVGA core and changes its renderer accordingly, mainly a blank render one.
2. Workaround the Ctrl-Alt-Del reset of Windows 2.x so that it switches back to VGA text mode correctly when using the 0xA000 64K aperture (in vid_svga.c).

SVGA core:
Re-organized the way the different timers are organized so that the XGA and 8514/A pollers can coexist with the SVGA timer without conflicts.

ATI Mach32:
Reworked the true color renderer and made it a Mach32 exclusive due to its differences from the standard one. Fixes wrong rendered colors in NT using the 32bpp renderer in RGB mode.

f48c50f4ba The delayed video changes of the night (January 20th, 2025) 
Generic SVGA layer:
Added function pointers of the banked mapping for use with add-on cards with their own mapping when the VGA card banked mapping is not active or viceversa (e.g.: XGA).

XGA-1/2:
1. Reimplemented Area Fill and Boundary Mode as best as possible.
2. Fixed conflicts with banked mapping with VGA clones.
3. Fixed inverted colors (again) on accelerated 16bpp mode under OS/2.

Video7 with ATI 8514/A add-on.
Added a workaround (BIOS issue? I don't know) that disables 8514/A mode and reenables VGA mode when needed. Fixes screen freezes and polling issues with various drivers for Windows and others.
