title: Google Maps API v3 MouseEvent return position of marker not mouse
body: <p>I have implemented a map with markers and listeners on the markers.</p>
  
  <pre><code>...
  google.maps.event.addListener(marker,'rightclick',function(event) {showRightClick(event, map, marker);});
  ...
  
  // Show Right Click Menu
  function showRightClick(event, map, marker) {
          var point = map.getCanvasProjection().fromLatLngToContainerPixel(event.latLng);
          var scriptInterface = getHeader();
          var screenX = point.x + window.screenLeft;
          var screenY = point.y + window.screenTop;
          scriptInterface.rightClick(marker.name, marker.objectid, marker.dimobjectid, screenX, screenY);
  }
  </code></pre>
  
  <p>But, when the listener triggers, the event latitude and longitude is that of the marker and not the mouse.  So, the right click menu I am trying to show appears at the bottom of the marker and not the mouse position.</p>
  
  <p>Does anyone know if this is a bug or expected behaviour?</p>
