Re: [csswg-drafts] [css-color-4] Premultiplication in cylindrical spaces and mixing (#11238)

> One reason that choices (1) and (2) are on this list is that I'm not sure how useful it is to do compositing in a cylindrical space. I'm happy to be pointed to evidence on this.

There are three useful spaces for compositing:

1. CIE XYZ (or equivalently, any unbounded linear-light RGB space) to get the right result
2. gamma-encoded sRGB, to get the wrong but web-compatible result
3. gamma-encoded device RGB (because you already have your pixels in that space and want to use the hardware), which also gives a similar wrong result to 2.
