This is a big patch and I'm having difficulty figuring out what
it's doing. Is it possible to split it up a bit?

thanks

Not really. It indeed does a few different things:
1. Removes fullScreenWindow
2. Changes mouse event handling.
3. Changes coordinate calculations.

Unfortunately we have to do these at once because how window is 
organized affects both of mouse event handling and coordinate calculations.
