If I sweep the control window over the graph window, it redraws properly
- *BUT* the X server might be providing backing store or save-unders, so
that no expose events are getting delivered (the server may just be
redrawing the newly-exposed area with the saved pixels).  It also works
if I minimize and re-maximize the window, but that may also involve
saved pixels.

Somebody should try it with backing store and save-unders turned off on
their X server.
