Green on Try. https://hg.mozilla.org/integration/mozilla-inbound/rev/aa73f5544e07 Should this have a test?

IIRC it broke existing tests when azure content was turned on.

It turns out that this is what regressed a few Canvas 2D tests, like http://philip.html5.org/tests/canvas/suite/tests/2d.path.isPointInPath.transform.2.html on various platforms.

They are reenabled now, but with these few sub-tests commented out. See bug 800658.

Anthony, I'm not really competent to debug this. Can I ask you to take care of it?
