Description Alex Christensen 2014-06-11 10:21:05 PDT 
WebGL 2.0 uses OpenGL ES 3.  We should be careful that code that uses gl.getExtension to query WebGL extensions does not break.  I'm not sure how this will be dealt with in the WebGL 2.0 spec, but I think if something was an extension in WebGL 1.0 and is no longer an extension in WebGL 2.0, gl.getExtension should still return the same value to ensure backward compatibility.

iOS 8 Beta 2 still does not alleviate the artificial constraints.

I think you intended this comment for another bug.
