[Openicc] Proof of concept, storing profile in X atoms

[Ross Burton]

Hi,

I've been investigating colour management recently, mainly as the photos
from my digital camera are in the Adobe RGB colour space and thus look
washed out when viewed on my sRGB display.

By reading this list and poking a bit I've got a trial implementation,
where an application at startup sets an ICC profile on a property of the
root window (as discussed on this list).  The atom I am using is
_ICC_PROFILE (format is 32-bit cardinals).  Applications can then obtain
this profile and use it to adjust images as required, to demonstrate
this I've patched the GNOME image viewer Eye Of Gnome.  It's so far
working quite well, so would appreciate some feedback on my approach,
and am wondering if there is any possibility of this atom being drafted
as a freedesktop.org standard, if there isn't another standard for this
I'm unaware of.

More details and the code can be found at:
