Any clues on how to do this in CLX?  I just tried some experiments with
using an EVENT-CASE with :timeout 0 and :discard-p t to scan through the
event queue, discarding all but the first expose event on a window.  But
returning T from the clause to indicate that the event should be kept
would also exit from the EVENT-CASE, so you'd never see whether there
are more expose events in the queue or not.  I tried doing a recursive
call to EVENT-CASE to look at the remaining events, but that seemed to
end up throwing out events it shouldn't have.  I'd appreciate seeing a
bit of code that actually works.
