  $("#map_tools_selng").attr( 'value', ne.lng() );
  $("#map_tools_nwlng").attr( 'value', sw.lng() );

  // Set Zoom Level
  $("#map_tools_zoomlevel").attr( 'value', HAR.map.getZoom()+1 );
  document.getElementById("map_tools_centerLat").value = HAR.map.getCenter().lat();
  document.getElementById("map_tools_centerLong").value = HAR.map.getCenter().lng(); 

  // All this junk below is for getting pixel coordinates for a lat/lng  =/
  MyOverlay.prototype = new google.maps.OverlayView();
  MyOverlay.prototype.onAdd = function() { }
  MyOverlay.prototype.onRemove = function() { }
  MyOverlay.prototype.draw = function() { }
