Elle,
It is not the critic who counts; not the man who points out how the strong
man stumbles, or where the doer of deeds could have done them better. The
credit belongs to the man who is actually in the arena, whose face is marred
by dust and sweat and blood; who strives valiantly; who errs,

In the current babl/GEGL/GIMP code base, I counted five files that
contain functions that require a conversion from RGB to XYZ:
1. gimp/plug-ins/common/decompose.c
2. gimp/plug-ins/common/compose.c
3. gimp/app/core/gimpimage-convert-type.c
4. gegl/operations/common/image-compare.c
5.
Unfortunately for hard-coded sRGB as PCS, the ICC profile
specifications are a moving target. Right now the ICC profile illuminant
is always D50. But in the next planned release of new specifications,
things will change:

GIMP is not the only project using GEGL; nor is it the only user

arbitrary counts of RGB spaces; which also GIMP need for having

Elle,
Time for you to stop making vaguely patronising remarks
Hmm, *who* has been making vaguely patronising remarks?

Yes, the majority of operations will operate in myfavoriteRGB space,

function properly. This isn't the case.

Hi,
I fully agree with Jehan and think it's essential
in a healthy software development process to scrutinize
and review things. Especially the whole color management
stuff is a topic that is not so clear to many of us and
