For in-a-window drawing, speedup should be substantial, though not nearly
as fast as OS 9 or Classic. This stems from the fact that we used to be
triple buffering our windows in the original Carbon code. Classic seems to
bypass the window server to draw directly to VRAM; there doesn't seem to
be a way to get this going in a macho-o or CFM/Carbon application yet,
though there is hope that Retained windows will come to the rescue here.
Retained windows should be able to draw directly to the screen when they
are not occluded.
