Update to WebVR 1.1

[spite]

From the new spec, and this https://github.com/w3c/webvr/blob/gh-pages/js/webvr-1-1.js

So that needs VRFrameData and the corresponding methods, right?

[spite]

Yes, right now it relies on the page using a polyfill (https://toji.github.io/webvr-samples/js/third-party/webvr-polyfill.js).

The blockers right now are #10 and similar problems that were found while coding the webvr-recoder. Since some properties in VRDisplay are read-only, everything needs to be wrapped and it's a big rewrite. Same with Gamepad API.

Adding VRFrameData is trivial, I'm just holding on to the spec changes while preparing the wrapper rewrite.

[AVGP]

Oh right, I see.
Just FYI: WebVR 1.1 has landed in Boris' polyfill directly: https://github.com/googlevr/webvr-polyfill/pull/149/files

So, yeah, let me know what I can do right now to help ya out! 👋

VRFrameData and VRDisplay.getFrameData implemented in 100da95

Seems to work ok, but there's some weird issue with webvr.info/samples and Canary at the moment. All other content in Stable seems to work.
