[csswg-drafts] [css-2015][css-2017][css-2018] List features cleared for shipping

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

== [css-2015][css-2017][css-2018] List features cleared for shipping ==
We have a policy of discouraging shipping implementations for anything which hasn't been cleared by the CSSWG, either by the spec reaching CR or by us resolving on an exception to indicate that we've reviewed it and think it's stable enough. It's easy to see what's in CR, it's harder to find the list of exceptions: we should put them in the snapshot.

Here's a start:

* Flow-relative equivalents of sizing, border, margin, and padding properties
* Transforms, Animations, Transitions
* min-content, max-content keywords for sizing properties

        as a pre-CR spec that hasn't changed in awhile is usually more out-of-date than stable.
