how big is the root window?
In any case rescale the image a priori and then store it in a pixmap.
It's big and it doesn't change. For efficiency sake you want the option
with the least work-per-refresh
(for example on expose events...)
On the performance side a question for Century:
Jordan, is the image rescaling coded for MMX as part of MicroWindows, or
is it the responsibility of the driver to do rescaling?
