How could a program which is _GEM_ not speed up? Seeing as the blitter
(As I understand how it works) speeds up the Line-A type stuff, and seeing as
GEM uses Line-A, wouldn't all GEM programs inherently be sped up? (Depending,
of course, on how much of it was GEM and how much was custom drawing).

I'm not entirely sure about the exact direction of the original
question, but: Those programs may be the only ones that EXPLICITLY use the
blitter, but all programs that don't use all custom output drivers would use
it if available, no?
