66 *		Given device-dependent or device-independent color

72 *		XcmsSuccess if it succeeded without gamut compression;
73 *		XcmsSuccessWithCompression if it succeeded with gamut
74 *			compression;
75 *
76 *		Since XStoreColors has no return value, this routine
77 *		does not return color specifications of the colors actually
78 *		stored.
