(A+B)-C mask operation I have found is quite useful (destination-out), but it is the only one of the relevant alpha Porter-Duff composite operations that was not included in the spec. E.g. I want to subtract a mask from both A and B.
Note the lack of an equivalent destination-out operation.
I can't think of a way to simulate it with existing operations (add, subtract, intersect, exclude).
