title: translationInView equal to 0 when fast panning using UIScreenEdgePanGestureRecognizer
body: <p>I created a test <a href="https://github.com/nico75005/TestQuickLowerSpanInLandscape" rel="nofollow">project</a> showing the problem. </p>
  
  <p>When I do a fast pan from the left or right edge, during the state <code>UIGestureRecognizerState.Began</code>, the <code>translationInView</code> is equal to (0.0, 0.0). This happens when you are in <code>landscape</code> and do the gesture in the lower half of the device (iphone 6 in my case) or when you are in <code>portrait</code>and do the gesture in about the 1rst third part of the screen (from the bottom).</p>
  
  <p>Is it... normal? I guess it's probably know but couldn't find anything.</p>
