Re: [Gegl-developer] Compositors

Note the comment at the top of that file:

/* SVG rendering modes; see:
 *     aA = aux(src) alpha      aB = in(dst) alpha      aD = out alpha
 *     cA = aux(src) colour     cB = in(dst) colour     cD = out colour

It's also probably useful to note that these operations are generated
by svg-12-blend.rb, so you might be better off looking there for some
of the code.

What source is used for the math? I see the original Adobe
reference uses different math for the compositors like
soft-light. Not sure which math to use, the one you guys have
in GEGL or the one in the Adobe reference, which is used in
Photoshop and After Effects, etc.
