[Bf-cycles] Potentially incredible fast rendering idea :-D

[Mike Farnsworth]

Thresholding like this is bound to have some pretty nasty failures.  Any
time you introduce any sort of adaptive criterion (whether spatial,
temporal, intensity, whatever) you will start to find failure cases.  This
one assumes too much, and so it would have a lot of failure cases where it
wouldn't refine when it should.

Welcome to the world of adaptive sampling.  It's not an easy problem to
solve. :)
