True.  Though setting variance to 0 might cause it to be slower than 
setting variance to a suitably low number and confidence suitably high; 
at least then POV can bail out when it actually attains that low variance 
and high confidence.  When variance is zero, you require it to use the
maximum number of samples for each pixel.
