NOTE: "Plus" does not use 'over' alpha-blending but uses a
special 'plus' form of alph-blending. It is the ONLY mathematical
operator to do this. this is what makes it different to the

+ otherwise equivalent "LinearDodge" composition method.
Note however that color channels are still effected by the alpha channel
as a result of the blending, making it just as useless for independant
