title: When Google Maps API calls "mapsbackend.loadMap" method as reported in API console?
body: <p>someone could explain to me WHEN GMap Javascript API calls the <code>mapsbackend.loadMap</code> method as reported in Google API console?</p>
  
  <p>Is it called when the first script is get from Google using "<a href="http://maps.googleapis.com/maps/api/js?key=" rel="nofollow">http://maps.googleapis.com/maps/api/js?key=</a>..." url?
  Is it called when all the GMap objects are dynamically loaded from Google server?
  Or is it called when the map is finally rendered on the screen? (in this case, the method is never called if the map container tag is <code>display: hidden</code> or <code>display: none</code>?)</p>
  
  <p>Thanks in advance</p>
