Owen was just optimizing it for GTK 2, try CVS GTK HEAD maybe. If you
do a render on every motion event it's going to eat 100% CPU no matter
how fast he gets it though - you normally get quite a few motion
events for a mouse movement...  if you don't use
POINTER_MOTION_HINT_MASK you'll quickly get behind and it will take
ages to "catch up", if you do use POINTER_MOTION_HINT_MASK the whole
point is to handle as many events as you can, which basically means
100% CPU.
