Of course it is much faster to redraw a rectangular window. We could provide
a fast algorithm for that and a slower one for non-rectangular windows. In
that case the application programmer can decide whether to use a rectangular
window or not. Another approach could be marking certain regions of the
windows as transparent.

That's just what I was thinking about.

I'm working on the quantum-Bethe-ansatz on an AdS3-string-background. That's
a quite special topic in string theory, concerning a recent theorem known as
AdS/CFT correspondence. It shows the duality between string theory and field
theory and could lead to a better understanding of unified theories and
quantum gravity.
