As always. Thanks for the references! Yes, related.

Yes, your debugging capability for normals. It's been on my todo list 
for a while. I plan to implement it as a special pattern so I can return 
the perturbed normals in addition to the raw normals.

I've already modified the yuqk aoi pattern to work with the full range 
-1 to +1 possible perturbed normals. I should try that now actually on 
the black ones... Ah, it didn't offer clue why things go black in the 
degenerate case - things are still black.

I'll need to do some debugging I guess.
