This was not the patch I had in mind. The idea was that every call of
update_map_canvas queues the rectangle in a struct in a list. At the
flush point (looks like this is flush_dirty) you clean this list of
queued areas. You do this by removing any areas which are inside other
areas. The remaining areas of the list are drawn with the code of the
current update_map_canvas.
