title: Extend Google Maps marker to animate smoothly on update?
body: <p>Using the Google Maps API v3 I've been able to update multiple positions of markers via an AJAX call. However, it lacks any transition. Code below:</p>
  
  <pre><code>if ( !latlong.equals( point.latlong ) ) {
      point.latlong = latlong;
      point.marker.setPosition(latlong);
  }
  </code></pre>
  
  <p>The drawback is that <code>setPosition</code> has no native animation method. Does anyone know any methods for extending <code>setPosition</code> so the marker can fluently "move" from it's old to new position? Or any methods available? I have not been able to find any documentation. Thanks!</p>
