If it relied on curses, it would be much easier to make the redisplay treat
each Emacs `window' as a real window on whatever the window system is (GTK
/ X / mswin / tty), which would make it so that you could get rid of the
current scrollbar placement code and let a geometry manager do it, etc.
I think that if you created new device methods for create_window,
move_window, set_window_size, set_window_scrollbar_policy, perhaps a few
more, then the redisplay mechanism would just have to worry about drawing
text for _1_ window, and you would have a new mechanism for managing the
window placement, etc.

I would be willing to help. I _really_ hate how the current redisplay
handles all of this.
