Follow-up Comment #3:

And somewhat belatedly, soft-light done!

As before the attached file should look like the W3C example in

http://www.w3.org/TR/SVGCompositing/#comp-op-soft-light

when saved as a transparent PNG which is then opened in something like
ristretto or eog, or another program that renders transparent images over
chequered backdrops.


David: (and anybody else reading this) could you please test _every_ blend
mode to make sure they're _all_ working correctly please? You can probably use
the attached files and the w3.org reference for a quick visual inspection,
adjusting the blend mode. I'm asking because I've refactored rather a lot of
the math the module uses internally...

(MyPaint has no "no background" mode yet, which makes visually inspecting what
happens when you composite into the void. Then again, even the GIMP does its
own thing here: looks like it uses src-in and not src-over for certain
comparable ops.
