Re: [fxtf-drafts] [compositing-2] 'lighter' vs 'plus-lighter' (#446)

Ohhh thanks for finding that! @grorg, do you think we need both `lighter` and `plus-lighter`? Could we just have `lighter` and `darker` and have them both clamp.

Yeah, otherwise it gets weird when going between premultiplied and the other thing.

Can a web API do that? Should I be seeing a difference in https://static-misc-3.glitch.me/composite-test/cap.html? If not, can you give me an example that shows it?
