ffenestri
- does not touch the  Squeak UI code
- requires the smallest changes to the VM we could find a way to make;  
basically the event input loop needed extending for some new events
- uses a fairly small plugin to provide a few new primitives (such as  
create/open/show/hide/close/move/resize/query)
- does not change the BitBLT system at all
