The fix that was in maverick was essentially a hack. We can't have it
upstream because it paints windows twice.

There is a smarter way to do the shadow clipping the way I have it
upstream, namely, you need to project the transformed window geometry
of windows below the shadow and set that to be the clip region of the
panel shadow. I know that the blur plugin does this (see
blur.cpp:projectRegion and blur.cpp:projectVertices)
