-        This can be done by querying the window server about the on screen
-        windows for their screen rectangle and window level.
-        The procedure used below is puts accuracy before speed; however, it aims to call

-    Notes:
-        -Calls into the Window Server involve IPC which is slow.

-        -On average, I suspect, most windows above ours are dock icon windows (hence optimization)
-        -Some windows above ours are always there, and cannot move or obscure us (menu bar)

-        -no way (yet) to deactivate direct drawing when a window is dragged,
