 // It is often desirable to automatically start vr presentation when
 // a user puts on the VR headset.  This is done by emitting the
 // Window.vrdisplayactivate event when the headset's sensors detect it
 // being worn.  This can result in WebVR content taking over the headset
 // when the user is using it outside the browser or inadvertent start of
 // presentation due to the high sensitivity of the proximity sensor in some
 // headsets, so it is off by default.
