Mach32 LFB changes (March 8th, 2025)
...
The Byte Write access of the LFB of the Mach32 was not correctly taking account of the subtraction of the address, this fixes possible graphics bugs using the LFB (Linear Aperture).

8514/A compatible changes of the day (March 6th, 2025)
...
1. Follow the Mach32 manual more closely regarding vblank support.
2. The subsystem status now takes account of the other bits more accurately.
3. The Mach32 PCI, when used with the ATI 68860 ramdac, has its own bpp's when in accelerator mode, separate from the VGA compatible side, so fix this accordingly.
4. Reset the vram when a mapping change occurs, should clear the messups in the ATI Mach8/32 accel video mode tests.

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.
