Re: [w3ctag/design-reviews] CSS Color: lab(), lch() (#488)

Also, a few examples of things that might need fixing (or new alternatives) that would be found by auditing the [list of things to audit](https://github.com/w3ctag/design-reviews/issues/488#issuecomment-610107610) to ensure that the platform has good support throughout for out-of-sRGB colors:
* (this one I'm pretty sure about) everything to do with [canvas pixel manipulation](https://html.spec.whatwg.org/multipage/#pixel-manipulation), including the [`ImageData` interface](https://html.spec.whatwg.org/multipage/#imagedata), to have variants that allow getting canvas data that's outside of the sRGB gamut
* the [algorithm for serializing bitmaps](https://html.spec.whatwg.org/multipage/#serialising-bitmaps-to-a-file), to ensure that it's possible to serialize any possible canvas accurately
* the [`<feColorMatrix>`](https://drafts.fxtf.org/filter-effects/#feColorMatrixElement) and [`<feComponentTransfer>`](https://drafts.fxtf.org/filter-effects/#feComponentTransferElement) filter primitives, to ensure that there are sensible ways to do those operations on colors outside of the sRGB gamut
