Thanks!

Confirmed; the patch seems to fix (1) and (2). That is, my application now
survives the filter() operation, and the results of simple kernels look ok.
However, lacking nice testcases I didn't check the output images for
correctness. 

For some reasons that I don't yet understand, trying to paint() the result
images is extremely slow (about 3 seconds per repaint for 640x480 ARGB
with ARGB DirectColorModel) and makes my app completely unuseable. 
For example, opening a menu triggers a few repaints, each of which takes 
3 seconds... 

Still, I'm closing this now.
