The main platform the clears and blitters were optimized for was PPlain/PMMX.
For PPro+, there's not a lot that can be done for the masked blits
(expensive branch mispredictions). Virtually no changes were done to the
16-bit code (only a few slight changes to the blit loop in blit.inc) -
iblit16.s was not changed, 16-bit clears were not changed at all (though it's
hard to tell from that -3%???). I considered working on the 16-bit code, but
was waiting for a reply on the alignment issue in the clears.
