Intent to Implement: Web Animations API

[Brian Birtles]

Summary: Allow web authors to inspect/debug/control running CSS (and
SVG) animations and create new animations

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=875219

Link: http://dev.w3.org/fxtf/web-animations/

Platform coverage: All platforms

Estimated or target release: late 2014

Preference behind which this will be implemented:
layout.web-animations.api.enabled


Background:
The spec is massive. A level 1 spec is expected to be carved out soon
covering a subset of the features. Initially, I plan to focus on
implementing just the subset needed to inspect and manipulate running
CSS animations and transitions (SVG will come later).

Blink recently decided to ship a different subset[1] but both subsets
will still be part of the level 1 spec. WebKit indicated they would
start work on Web Animations but I think it has stalled recently.[2] IE
says, "under consideration".[3]


Best regards,

Brian
