title: Google maps zoom in on marker
body: <p>I'm using the Google Maps API. When I click on a map marker, I want the map to zoom in one step, but maintain the marker's position relative to the window. </p>
  
  <p>This is similar to when you use the mouse wheel to zoom: the zooming is towards the current cursor position.</p>
  
  <p>The map.setZoom() function zooms relative to the center of the map. This is not what I want.</p>
  
  <p>Can't find any simple solution to this, anyone has a clue?</p>
