The net-color spec from the libXcm repository is renamed. During a great conversation with Martin Gräßlin from KWin at oSC rwx³ he pointed out, that the _NET_ prefix is reserved inside the Xorg atom name space. So I decided to rename all atoms in the applications known to me, which use the net-color spec. The renaming went on fast and all apps work again as expected in git.
The new spec is called X Color Management. It contains the color regions in Xorg description and the used device profile for Linux desktop colour servers.
Affected are libXcm, Xcm, Oyranos, CompICC and CinePaint.
