1398037 - [meta] Ship more of Animation interface

Status: NEW

(Core :: DOM: Animation, enhancement, P5)

Description

[Brian Birtles (:birtles)]

This is a tracking bug for shipping the next subset of Web Animations API.

Specifically, the following:

1) 'ready' and 'finished' promise
2) Support for omitting the 0% or 100% keyframe and using the underlying value
3) Extensions to property-indexed keyframes[1]

I imagine we will need at least the following bugs:

* Create a pref for switching these parts on
* Convert type of Keyframe.offset from double? to double (pending spec changes)
* Implement extensions property-indexed keyframes (pending spec changes)
* Implement async playback rate changes (pending spec changes)
* Bugs for tidying up existing tests
