title: Not able to find the interactive gesture events like igiZoom, igiPan or igiRotate for vcl component in delphi XE7
body: <p>I want to use the interactive gesture event for my windows application(for mouse and touch).
   Although <strong>OnGesture(Sender: TObject; const EventInfo: TGestureEventInfo; var Handled: Boolean);</strong>
   event is triggered, while zooming with two finger touch,  I am always getting EventInfo.gestureId is 0. But I am getting the standard gestures. 
  Note : I am using Delphi XE7 for development and windows 8.1 touch device for testing. </p>
  
  <pre><code>procedure TForm1.GISGesture(Sender: TObject; 
    const EventInfo: TGestureEventInfo; var Handled: Boolean);
  begin 
      if (EventInfo.GestureID = igipan) or(EventInfo.GestureID = igiZoom)  then
      begin
        ShowMessage('zoom or pan');
      end;
  end;
  </code></pre>
  
  <p>Here EventInfo.GestureID is 0 whenever I tried to zoom with two finger or pan.</p>
