I'm looking for a color gcontext function which says essentially:

	"If the source is not white, let the result be the source.
	 If the source is white, let the result be the destination."

I can't seem to find a gcontext function which, by using its
bit by bit techniques, yields the desired results.  Am I missing
something obvious?
