In WebMediaPlayerImpl's destructor, when using a VideoLayer, we call StopUsingProvider to make sure that we can safely destroy the VideoFrameProvider (|compositor_|).
We will need to address this relationship once the class that will be pulling the frames from the VideoFrameProvider (to be implemented as VideoFrameSubmitter atm) is designed/implemented.
