12a57ffeac Changes to 8514/A compatible stuff (November 2nd, 2024) 
1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled).
2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command.
3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.
