I guess I was hoping for a minimal patch that just added an XYToWindow
screen function and then had the existing XYToWindow call that so that
all existing XYToWindow calls would 'just work'. I'm also not quite sure
what the device argument to the new function is for; that really isn't
part of this operation.

How about this version instead?
