actually you can quite easily - use visibilitynotify events :) they
will tell you if you are fully obscured, partially obscured or
completely unobscrued - regardless of what the wm may or may not do. if
the wm like the ides of hiding a client window by moving it to 10000,
10000 - so be it. the visibility notify stuff still works.
