Is this necessary?  This means we'll always boot up the
ScreenOrientationController...  I guess that's necessary because
ScreenOrientation is a supplement and we don't necessarily boot up
ScreenOrientation when someone starts listening to screen orientation events... 
:(

Yes, I need to make sure we construct the ScreenOrientationController at some
point. Optimally, we would construct it only when someone starts listening for
orientationchange events on screen but I am not sure that's currently possible
(at least I don't know how).
