When scaling is enabled, it stops doing set_size_request()s.  For 
thumb-nail scaling, I would set_size_request() manually.

I've tested smaller scaling, it works very well and is also a very neat 
demo.  The mouse even works as you would expect it too :-)

The GTK sizing stuff is very bizarre.  I've fought with it a lot.  I'm 
not sure there's an ideal way to deal with it other than doing 
set_size_request.
