title: How to pick with Geographic Coordinates?
body: <p>So far, all of the examples I've seen for picking entities/features have been based on passing the window position to the pick method of the scene object. Example:</p>
  
  <pre><code>var pickedObject = scene.pick(movement.endPosition);
  </code></pre>
  
  <p>Is it possible to pick an object with another method which takes geographic location as its parameter?</p>
