[csswg-drafts] [css-transforms-2] Is addition/accumulation for the Individual Transform Properties specified anywhere? (#4355)

stephenmcgruer has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-transforms-2] Is addition/accumulation for the Individual Transform Properties specified anywhere? ==
Not sure if I'm just going blind, but reading https://drafts.csswg.org/css-transforms-2/#individual-transforms I can't see a definition of the additive or accumulative [composite behavior](https://drafts.csswg.org/web-animations-1/#effect-composition) for the individual properties ('scale', 'translate', 'rotate')? There's a section for transform-list, but that isn't relevant (afaict) for the individual properties.

I've attempted to reverse-engineer it from [the WPT test](https://wpt.fyi/results/web-animations/animation-model/animation-types/addition-per-property.html?label=master&label=experimental&aligned&q=web-animations%2Fanimation-model) but it isn't always clear. E.g. it seems reasonably clear that 'scale' has an additive behavior of multiply, but it's accumulative behavior isn't clear from the examples.
