title: How to make draggable remember it's location in React Native
body: <p>I'm learning about the animation and panresponder apis in react native. Following <a href="http://moduscreate.com/animated_drag_and_drop_with_react_native/" rel="noreferrer">Animated Drag and Drop with React Native</a> and the <a href="https://github.com/crysfel/DragAndDrop/blob/master/app/Viewport.js" rel="noreferrer">source</a></p>
  
  <p>I want to extend the example so that you can drag the circle without having to reset it. Currently the code animates the circle back to the center of the screen and relies on the panresponders dX/dY values.</p>
  
  <p>my best guess is I have to change something in <code>onPanResponderMove</code></p>
  
  <pre><code>  onPanResponderMove: Animated.event([null, {
      dx: this.state.pan.x,
      dy: this.state.pan.y,
    }]),
  </code></pre>
  
  <p>What do I need to change in the source so if I comment out the <code>onPanResponderRelease</code> logic the circle properly drags around the screen?</p>
  
  <p><code>getTranslateTransform()</code>?</p>
