Yeah, I was quite quick with that. But given that I wouldn't have time
to check it in for some days, and also given that I already tested this
to a certain extent, and we have CVS and testers and such, I just
checked it in.

Thank you. The performance gain especially seems to show up on complex
GUIs with lots of elements. For instance the foxhunt game (it has no
complex GUI, but lots of buttons, around 100 or more). The situation
before was, that the painting went from the RootPane down to _every_
button, the clipping sorted it out what to paint, but still every button
had to be visited. That took a long time, everytime when you clicked a
button you had to wait some seconds before the GUI reacted. Now this
little game is quite smooth.
