I almost posted something close to this until I realized that I didn't know
if the last n SWP structures were definitely for me.  Just out of curiosity,
what happens in the case where the frame window is already subclassed by
some other set of special controls (say you're using a library that provides
a frame with other new controls)?  Are your own SWP structures still last,
or is there a way to definitely find those that were allocated for your use
(check for 0 HWNDs maybe)?
