Re-2: [Radiance-general] CIE TC 3.33

[Greg Ward]

I'm still looking at this.  My main hesitation is that the changes,  
while improving the accuracy for disk sources at close quarters, will  
increase the number of samples by a factor of six for distant disk  
sources.  That's a trade-off I'd rather not make, so I'm thinking of  
how we might get around it.

Best,
-Greg
