Someone was asking a while ago about creating repeatable patterns in POV.  I
think I have come up with a manageable solution without resorting to
mirroring the pattern.
The attached images are of heightfields generated using the method tiled
together. HF1 is just the hf with the image_map, HF2 highlights the the
individual hfs. HF3 shows a closeup at the corner seam of 4 hfs.
Comments/questions/problems (before I post the source).
