A reverse transform from the D50 partialy adapted "source" state using
a varient von Kries transform to a fully adapted space, then a
forward transform from that space to the target illuminant space. For
the moment I'm going to ignore the surround effect and just go for
assuming a neutural background.
Its really not ICC management but adapting the picture to be viewed
correctly under a different illuminant. I've almost finished my Java
source which can transform from one illuminant to another. When its
done I can post some samples we can print out and evaluate. If it
works well I can re-write in C++ and consider what to do with it :-)
