Summary

1. Remove more hacks usually placed for stuff to make them work, now stuff works per manual.
2. Pixtrans reads are no longer written in the accelerator function per manual. Warning: I still don't know how to properly fix the 8514/A bug on win2.x paint/pbrush, the commands are fine as well as the rop/mixes and the coordinates as well, I need help for this.
