	246	Creates a new pattern consisting of elements of <parameter>font</parameter> not appearing
	247	in <parameter>pat</parameter>, elements of <parameter>pat</parameter> not appearing in <parameter>font</parameter> and the best matching
	248	value from <parameter>pat</parameter> for elements appearing in both. The result is passed to
	249	FcConfigSubstitute with <parameter>kind</parameter> FcMatchFont and then returned.
