I think I'm finally zeroing in on the causes of my headaches-- it looks like 
the image that CI is spitting back to me is using 8 bit floats.  Actually, I 
think they're 8 bit fixed point values because I'm limited to the range of 
[0,1].  My Core Image patch won't give me an image back with any value less 
than 0.00392 (which is about 1/255).

0.002 gets rounded up to 0.00392, and dividing that number in half gives me 
zero.

The Core Image docs say it treats everything like 128bit floats, so am I facing 
a hardware limitation or a QC limitation?  Is there anyway to  get more 
resolution?

Thanks--
 Greg
