"Simple" things seem to work well again.

I still see all sorts of problems with JSplitPane. (In my image viewer, both
the JTree with the filenames and the main image canvas seem to randomly
overwrite parts of the split pane dividers, and sometimes things are blit into
wrong regions of the viewports. Probably some wrong clip remaining somewhere in
JViewPort.)

The menu-overwritten-issue is still there. I have no simple testcase, but here
are the steps to reproduce it:

1. Download  
   http://tams-www.informatik.uni-hamburg.de/applets/hades/archive/hades.jar
2. Run jamvm -jar hades.jar
3. Select menu > help > demos > clockgen
4. Wait two seconds until the demo begins
5. Try to open a menu
6. I personally like menu > layers the best: somehow two different parts of the 
   menu are redrawn when the LED connected to the upper clock generator is 
   updated :-)
7. The component uses its own backbuffer, and calls repaint(x,y,w,h) with
   handcalculated screen coordinates during the animation repaints.
8. Any ideas on how to debug this?
