Yes, it's a shame that you never submitted this for inclusion. It
could have become part of the 2.2 release.

Let's try to implement this in small steps then. As a first step I
would like to add a couple of options to the preferences to allow
users to define default locations for color profiles, to
enable/disable color management and to set a number of default
settings. Stefan DÃhla sent me a patch last year that implements this
and I will probably base the changes on that. The settings he
suggested are:
- use CM or not
- display profile
- default workspace profile
- default rendering intent for color conversion
+ from workspace to display (default set in display profile)
+ from workspace to printer (should default to
* perceptual for pictures
* relative colorimetric for most other work)
- default cmyk-profile (is later used to convert RGB->CMYK)
- default profile path (/usr/share/color/icc/ and ~/.color/icc/)
As soon as we have such settings, we need to figure out a way to make
them available to plug-ins and modules. We also need an API to access
the color-profile attached to an image.
