Thanks.
I'm still unsure as to why we need two versions of these MMX clear
routines for screen vs. memory bitmaps: I can't measure any difference
from using the segmented version all the time, and that halves the size
of the code. Robert: do you have any solid measurements to prove that
this optimisation is useful? If not I'm going to take it out.
