widget should be able to draw itself
A clever widget can draw only the parts of it that are specified in the region argument. A not so clever widget can safely ignore the region argument and draw the entire widget area.
Keep in mind that double buffering is already implemented and you can't gain anything by reimplementing it again at this level.
