I don't know the source of POV, but

Looking at the picture I think the effect comes from some
clipping-effects of the different rgb-values or some
non-continueities (you know what I mean) of the Gamma-function
with negative values ... (How is gamma defined for negative
values ???)

I think, the question is: When is it applied? Before or after AA
??
