In general you might be right, but in the case of resizing a window 
boarder, or drawing the cross hair for bounding box select, It speeds 
things up a great deal.

In software openGL my amd64 3500 took about 10 seconds to finish drawing 
the resize boarder XOR, flickering line before it refreshed the window.

Since its checking for mouse events anyway in the loop, I dont see why 
it shouldent check to see if the mouse has moved in before it bothers 
with a redraw.
It does speed things up a great deal, no flicker lag.
- My patch.
