Huge fixes to 8514/A compatibles:
1. Properly implemented polygon filling in the BitBLT side of the ATI 8514/A compatibles (Mach8/32), this allows games like Mj8514 and demos like HDIDEMO from IBM to run under ATI's hdiload 1.1 properly. 2. Finally figured out the polygon filling command in the IBM one about read and write masks (Command 5 and Command 2 with polygon filling bits on, currently only for the read mask one), this allows the above samples to render properly with IBM's original hdiload 1.0 from 1987.
