Let's say that I want to blit an image to the screen in portrait mode --
should we have the user make an offscreen image (GrNewPixmap) and somehow
have him place it sideways, or store all images in canonical coordinates,
and have the Blit be smart enough to do a non-sequential mem-move()?
Would the approach of having the driver do this last second be too slow?
