Description Søren Sandmann Pedersen 2005-12-08 07:38:12 UTC 
If a redirected window is completely covered by a non-redirected sibling, and 
the redirected window is raised on top of the non-redirected one, the redirected
window has its background painted, and gets sent expose events.

More details in the comments in the soon-to-be-attached test program.
