SDK / exoplayer

Other properties of SphericalGLSurfaceView (e.g., setDefaultStereoMode)
are not plumbed through the PlayerView components, and it doesn't scale
to plumb through all properties of all of the SurfaceView types.

Applications can instead do:

```
((SphericalGLSurfaceView) playerView.getVideoSurfaceView())
    .setUseSensorRotation(useSensorRotation);
```
