	Added basic support for the proposed ICC Profiles In X Specification
	(http://burtonini.com/temp/xicc-specification-0.1.html).

	* libgimpconfig/gimpcolorconfig.[ch]: added a configuration option
	"display-profile-from-gdk", default to TRUE.

	* modules/cdisplay_lcms.c: try to retrieve the display color
	profile from the "_ICC_PROFILE" profile on the default screen's
	root window.
