I just managed to rewrite ingo's df3 erosion idea for heightfields (I hope i
understood it right, i'm not totally sure) and it works really good!

The following 3 pictures are my first try: the first one is the original, the
second one is after 6 runs and the third after 12 additional runs (each run
taking only 240 ms on a 128x128 HF)

There probably is some more work to do (for example the edges) but IMO, it looks
really promising.
