+A0 will supersample even when there is no difference in the initial 
samples. +A0.0001 will only supersample if there is a difference greater 
than the given threshold, and it's those zero-difference pixels that are 
causing a problem.
It might be useful to have some way of forcing POV to supersample to 
some level before going into adaptive mode, making it more likely to 
find these pixels while wasting less time on fully supersampling pixels 
which really don't need it.
