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.
