Re: [fxtf-drafts] Add plus-lighter to mix-blend-mode and background-blend-mode (#444)

That's the part I'm unsure about. The text for lighten says, "The backdrop is replaced with the source where the source is lighter". Are we doing source over compositing as defined below :

co = αs x Cs + αb x Cb x (1 – αs), where

Cs = max(Cs, Cb) via the blending operation
Cb = same Cb as the blending step
