title: Does the Qt Quick 2 Scene Graph sync to vsync on EGLFS?
body: <p>I am studying about Qt Quick 2 in Qt 5.1. It is cool. However, I do not get it about Scene Graph feature. If I just create Flickable, put a bunch of Images to it, and show this in QQuickView on embedded device with EGLFS backend - am I using the Scene Graph or not? </p>
  
  <p>If yes, why do I see tearing - Scene Graph should be VSynced?</p>
  
  <p>If not - what should I do to use it with Flickable? Or does it mean I should implement all from scratch?</p>
  
  <p>My app is basically allowing to browse an endless generated image.</p>
