Rotation is best done when rendered in GPU, added the shader code which rotates the frame. For renderers which don't support rotation, the rotation will be done before sending down the frame to render. By default, assume renderer can't do rotation. Tested with peerconnection_client on windows, AppRTCDemo on Mac.
