Ditto. Let's move CanvasRenderingContext to the oilpan heap and remove these
persistent handles in a follow-up CL.

[sof, 2015/08/04 06:20:45]

It's an ActiveDOMObject, so it'll have to wait until the big switch.

[haraken, 2015/08/04 06:35:40]

What prevents us from shipping oilpan for ActiveDOMObjects? As far as I
understand, it's safe to ship oilpan for objects that inherit from
ActiveDOMObjects without shipping oilpan for ActiveDOMObjects. In fact, we did
this for MediaDevicesRequest etc.

[sof, 2015/08/04 06:37:58]

It's associated with an HTMLCanvasElement..

Acknowledged.
