[csswg-drafts] [css-backgrounds-3][css-images-4] Should background-image animation be discrete or follow interpolation advice from CSS Images 4? (#12075)

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

== [css-backgrounds-3][css-images-4] Should background-image animation be discrete or follow interpolation advice from CSS Images 4? ==
The [`background-image`](https://drafts.csswg.org/css-backgrounds/#propdef-background-image) property is currently specified as having "`Animation type: discrete`", which seems to indicate that it should follow the [discrete](https://www.w3.org/TR/web-animations/#discrete) rules defined in Web Animations.

At the same time, CSS Images 4 defines general [interpolation for images](https://www.w3.org/TR/css-images-4/#interpolating-images) that seems like a nicer behavior as you get things like cross-fades and nice gradient interpolation.

I propose updating `background-image` to allow using the default `<image>` interpolation from CSS Images 4.
