[fxtf-drafts] Add destination-out for mask-composite [css-masking-1] (#488)

Azmisov has just created a new issue for https://github.com/w3c/fxtf-drafts:

== Add destination-out for mask-composite [css-masking-1] ==
(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.

I can't think of a way to simulate it with existing operations (add, subtract, intersect, exclude).
