There's more. lcms1 carried the icc34.h header that defines the ICC format.
It's included via lcms.h and we depend on it for functionality that the lcms1
API doesn't provide.

I have some hope that the lcms2 API will be sufficient for this functionality,
otherwise we may have to carry this header ourselves.
