[Openicc] GoSoC 2011: CPD and Softproofing

[Ann McCarthy]

"Does it make sense to embed it into the ICC profile itself (i.e., changing
the profile on disk file, and changing the checksum)"
The driver settings that affect the color behavior of the printer should be
installed into the printer profile as it is built.
So this is not a post-build change to the profile -- it is a fingerprint of
the appropriate settings of the associated color processing path and the
printer that should be instantiated anytime that profile is used.
Conversely, for any print job, when the user selects the values of all of
the print parameters and selects the media to be used -- those selections
point to a profile.

Keep in mind that the profiles for printing are not 'printer profiles' ---
rather they are print condition profiles. The selection of the correct
profile for a print job depends on the paper, ink, and other driver settings
as well as the print device itself.
