title: google maps api v3 + infoBubble in markerClusterer
body: <p>I was trying to add an infoBubble to a markerCluster in the 'clusterclick' event but the infoBubble.Open method ask for a 'marker' parameter to bind with. The problem is that a markerCluster is not a google.maps.Point so it's not posible to bind the infoBubble to it.</p>
  
  <p>I assigned the possition of the markerCluster to the infoBubble but the infoBubble redraws in the new position moving the marker from its possition.</p>
  
  <p>Has anyone had the same problem? Is there a solution without modifing the original infoBubble code?</p>
