Oh sorry, I guess I saw your code on the transformation between openexr's 
chromatics and icc color profile, and I did extrapolate with my reading on

well it's my understanding that lcms support floating point, but it's really 
unclear to me what happen for bit depth > 16. I think that I saw a marti

would caused a lost of data.
