Rather than initially place pixmaps in framebuffer based on a size
heuristic, delay the decision until the first
kaaPixmapUse{Screen|Memory}, and put it in framebuffer if UseScreen was
called. Provides a significant improvement in cairo speeds (100%
speedup in cairogears here) and is likely to improve text performance
as well.
