Tom, Andrew, Steve etc are all right. The algorithms work, everyone is
doing their best, but the ICC systems approach is simply too complex to
implement interoperably. Things might work if there were a single centrally
maintained reference implementation that was used by everyone for color
processing, but the presence way of doing things by "standard" is a
guarantee of failure by finger-pointing
