Yes, this is a worst case ;-). Hence "acid test". In other respects 
this test is optimal, since all updates have a high locality. To test 
that you need to draw a lot of diagonal lines giving big update 
rectangles or ploting randomly to the screen.

Where did you plug that in?


Regions don't affect performance that much. Rectangles tend to grow too 
fast. Consider two small updates: one at 0 at 0 the other at 800 at 800 
moving 64000 pixels instead of a few.
