David Parks 198fa063c2 Bug 1477756 - Initial out-of-process WebGL implementation. r=mccr8,handyman
Splits WebGLContext into ClientWebGLContext and HostWebGLContext.  The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process.  At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.
