Is there a simple way to force MCL to wait until a window has repainted all of
its existing contents (after uncovering it from beneath other windows) before
drawing anything new in that window?  Say in a sequence like:

(window-select *buriedWin*)
(frame-rect *buriedWin* 10 20 10 20)

I don't think querying the VsRgn helps.
