I confess considerable ignorance on this topic, but isn't there also a tool for 
copying memory blocks?  If so, couldn't it be used to copy the offscreen bitmap
into the memory used for display?  This would seem much changing whole page displays (assuming one wasn't doing windows, menus, etc.,
in which case you could cause one heck of a lot of problems).
