When running compiz, things will slow down; we don't yet have an
efficient mechanism for transferring data from the window pixmap to the
texture. I'm a bit surprised that it paints in the wrong place though;
that "shouldn't" be possible. I haven't tried it recently though.

Performance can be improved; the pixel shader program that we wrote has
some obvious areas for performance improvement. Plus, it would be fun to
have it use a longer filter, which should improve appearance compared to
the simple bi-linear interpolation it is doing today.
