Re: [fxtf-drafts] [css-compositing-2] Remove plus-darker (#447)

@jakearchibald Would you consider advocating for `plus-darker` to be brought back into the spec and/or implementation? It's extremely useful for increased vibrancy of translucent materials, which are becoming more common on the web thanks to the power of filters and blend modes. Apple uses both `plus-lighter` and `plus-filter` blend modes across all of their operating systems, iOS in particular.

Here's an example (taken directly from [Apple's macOS Sketch Design Template](https://developers.apple.com/design/resources/)) where `plus-darker` on WebKit boosts vibrancy and legibility:

It also seems silly to only implement `plus-lighter` without its opposite!
