Just an update. I rewrote the existing Gimp lcms.c plug-in to use
lcm2. It seems to work just like the current Gimp plug-in. If anyone
is interested in testing it, I can supply the code.

As explained here:
(see summary at bottom of page), there are some coding issues to be
resolved before attempting to make the lcms2 plug-in do high-bit-depth
color conversions. So dealing with the coding issues is my next step.

Also, has anyone seen this Ubuntu bug report?
Completely replace lcms1 by lcms2 in Ubuntu

Kind regards,
