title: Hybrid & Terrain mapTypeIds shadowed in mapTypeControl
body: <p>Starting to learn Google Maps, was playing a little with it when I crossed one little quirk I though I would share should anyone have an idea about its cause and solution. </p>
  
  <p>Here's the thing : I try to show the <strong>TERRAIN</strong> and <strong>HYBRID</strong> map types on the map type's control, they show up fine when I only add them but once I add <strong>SATELLITE</strong> and <strong>ROADMAP</strong> types these last two take over, the first two will not be shown. </p>
  
  <p>Here is the minimal code : </p>
  
  <pre><code>mapTypeControlOptions: {
              mapTypeIds: [
                  google.maps.MapTypeId.TERRAIN,
                  google.maps.MapTypeId.HYBRID,
                  //google.maps.MapTypeId.SATELLITE,
                  //google.maps.MapTypeId.ROADMAP
              ]
          }
  </code></pre>
  
  <p>So if I un-comment the last two lines, the first two are as if not there!</p>
  
  <p>Is that normal behavior ? Guess not, so what's wrong ? Any solution ? </p>
