imageDataColorSettings should be optional.  I am okay with doing that in another
CL, but please file a crbug for it.

This cannot be done now, as the call without ImageDataColorSettings parameter
already exist and cannot go behind the flag. I filed a bug: crbug.com/711886.

Same here.

Addressed in the same CL.

     // Should be merged with WebGL counterpart in CanvasRenderingContext, once no-longer experimental
