title: QML MultiPointTouchArea Passthrough
body: <p><strong>Short Version</strong><br>
  Is there a way to in QML only to re-emit / ignore touch events selectively using the <code>MultiPointTouchArea</code>?</p>
  
  <p>OR</p>
  
  <p>Is there a way to block multitouch events via QML from the <code>QtWebEngine</code>?</p>
  
  <p><strong>Background / What I've Tried</strong><br>
  I'm helping with a QT application that uses the <code>QtWebEngine</code> 1.0 and when a multitouch gesture is applied to it, it crashes.</p>
  
  <p>My initial plan was to drop a <code>MultiPointTouchArea</code> in front of the WebEngine and consume all of the gestures that were greater than 1 touch.  I was hoping to achieve this solely in QML (below) and the touch events less than two (single finger / mouse) would fall through to the WebEngine.</p>
  
  <p>It didn't work :|  All of the touch events were consumed by the <code>MultiPointTouchArea</code>, which was tested by adding <code>TouchPoints</code> with rectangles around them to see which ones were firing.</p>
  
  <p>To confirm that it wasn't WebEngine just not responding, I put a second MultiPointTouchArea under the min:2 one and was never able to it's touch events. </p>
  
  <pre><code>MultiPointTouchArea {
      z:10
      anchors.top: parent.top
      width: parent.width
      height: parent.height
      enabled:true 
      mouseEnabled:true
      minimumTouchPoints: 2
      onPressed: { console.log("multi touch pressed"); }
  }  
  </code></pre>
