8514/A compatible changes of the day (April 2nd, 2025)
...
1. Aliases are aliases, period.
2. Actually make the ports using bit 15 of their range use the command FIFO.
3. Improved the special ATI command 0xc2b5 in the IBM bitblt side, fixes cursor issues in 24bpp mode using OS/2.
4. When the FIFO is empty, clear the busy and available flags.
5. Also reapply a workaround for 24bpp foreground color patterns in ATI command Scan To X command, fixes patterns in OS/2 and possibly elsewhere.
6. Accelerated HiColor mode, in the IBM passthrough mode, should always be enabled, for now, as well as the Extended ATI Mach32 8bpp mode when prompted, fixes OS/2 booting into the GUI in HiColor mode.
7. Dummy data path configuration values on direct linedraw should not trigger a pixtrans read when it's not needed, fixes possible hang ups in IBM/ATI mode when the busy flag remains enabled.

Major changes on the 8514/A side again (March 30th, 2025)
...
1. The DX/DY coordinates for BitBLT are now signed again, fixes 8514/A cursor issues.
2. Made the busy/data available processor statuses more like the ATI one for more stability and no stalls, fixes Windows 3.x and IBM OS/2 1.x (possibly later ones too) that use the built-in 8514/A driver.
3. Made the mode switching clearer (through a note) regarding the shadow sets, this should make every program happy, I hope.
4. In the Mach32 series only, a first load of the CRT sets also initializes the GE offsets if the corresponding bit is set, fixes Mach8/32 mode tests in their eeprom and demoai with hdiload from ATI/IBM.
