Description Andy Estes 2012-01-30 12:13:55 PST 
<http://trac.webkit.org/changeset/106274> added a new CompositeOperator called CompositeDifference. In CoreGraphics, this maps to kCGBlendModeDifference (see <http://developer.apple.com/library/mac/#documentation/GraphicsImaging/Reference/CGContext/Reference/reference.html#//apple_ref/c/tdef/CGBlendMode>).
