title: Google maps Polygon question
body: <p>The following is an example of how to greate a polygon in the google maps API.
  <br />What is the purpose of latOffset and lonOffset? 
  <br />We're creating an array of points to make a polygon, but what exactly is the offset doing?</p>
  
  <pre><code>var map = new GMap2(document.getElementById("map_canvas"));
  map.setCenter(new GLatLng(37.4419, -122.1419), 13);
  map.addControl(new GSmallMapControl());
  GEvent.addListener(map, 'click', function(overlay, latlng) {
    var lat = latlng.lat();
    var lon = latlng.lng();
    var latOffset = 0.01;
    var lonOffset = 0.01;
    var polygon = new GPolygon([
      new GLatLng(lat, lon - lonOffset),
      new GLatLng(lat + latOffset, lon),
      new GLatLng(lat, lon + lonOffset),
      new GLatLng(lat - latOffset, lon),
      new GLatLng(lat, lon - lonOffset)
    ], "#f33f00", 5, 1, "#ff0000", 0.2);
    map.addOverlay(polygon);
  });
  </code></pre>
