I've added preliminary (and yet untested) support for this to GIMP in
CVS so that we can play with it. If anyone's interested, the code for
retrieving the atom can be written entirely in GDK, there's no need to
use XLib for this:


      GdkAtom    type;
      gint       format;
      gint       nitems;
      guchar    *data;

      g_return_val_if_fail (GDK_IS_SCREEN (screen), NULL);

      if (gdk_property_get (gdk_screen_get_root_window (screen),
                            gdk_atom_intern ("_ICC_PROFILE", FALSE),
                            GDK_NONE,
                            0, G_MAXLONG,
                            FALSE,
                            &type, &format, &nitems, &data) && nitems)
        {
          cmsHPROFILE *profile = cmsOpenProfileFromMem (data, nitems);

          g_free (data);

          return profile;
        }
