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

@cabanier I'm a bit confused about how blend-mode vs compositing-mode are supposed to be different.

There are existing blend modes which define how the source and backdrop color values should be combined (the blending step) and then how this combined result is modulated by the backdrop alpha (the compositing step). For example, the lighten blend-mode states something similar to what we want to do with lighter, the backdrop is replaced with the result of blending the 2 color values instead of any further compositing operation. Is that not a valid way to specify a mix-blend-mode?
