Re: Compositing math in SVG

Hmm actually you are right, that does match the Adobe reference. But I
found many other sources that don't, for example the formula you use for
overlay here:

https://dvcs.w3.org/hg/FXTF/rawfile/tip/compositing/index.html#blending

is different than the one they use in GIMP:

http://docs.gimp.org/en/gimp-concepts-layer-modes.html

There are no conditionals there, just one formula. A comment from you on
this would help a lot !

Thanks
