This is somewhat disturbing to me. Using the pixmap plot routines is just
way too slow to do anything fancy. Allocating a writing to a programmer
supplied image buffer is just such an often used operation in games, demos,
and anything else that needs to do a lot of changes from frame to frame.
Saying that one must use ave/ave/pix/plot to draw your image is just
stupid IMHO. How does Tao's port of Quake and Doom do it?
