	     Everything works well until I re-size the window (via uwm).  When I
    do, I get an ExposeEvent, followed by a Configure and another Expose.  This
    causes the program to redraw the contents of the window twice, the first time
    scaled wrong.

uwm puts up this little popup right over your window.  When uwm unmaps it, you
get the first exposure.  If the servers implemented save-unders, this wouldn't
be a problem.  If anyone would like to contribute public save-under and/or
backing-store code ...
