Which isn't necessarily the same one that the mouse is over either.

How would this work: when the mouse cursor leaves the tracking  
rectangle for a the window, the "mouse window" is set to NULL, when  
the mouse cursor enters the tracking rectangle of a window the "mouse  
window" is set to that window?
This would correspond with how mouse cursors behave in ex_mouse_cursor.

Cool, that way we can move windows around and make them dodge the  
mouse. I can see a great game of "catch that window!"
Ok, maybe not. If we're going to report the position relative to the  
root window, should we also report the coordinates of the upper left  
and lower right coordinates of an Allegro window? Or can we already do  
that?
