title: How to center map in gmaps4rails?
body: <p>i want to display a map centered to a specific location.
  In my controller, I use</p>
  
  <pre><code>@gmapsoptions = {
       "map_options" =&gt; {"center_latitude" =&gt; 40, 
                         "center_longitude" =&gt; 73,
                         "detect_location" =&gt; false,
                         "center_on_user" =&gt; false,
                         "auto_adjust" =&gt; false,
                         "auto_zoom" =&gt; false,
                         "zoom" =&gt; 8 }
                   }
  </code></pre>
  
  <p>and in my view i use</p>
  
  <pre><code>&lt;%= gmaps(@gmapsoptions) %&gt;
  </code></pre>
  
  <p>It renders the map just fine, but it is not centered on the location specified above but on "0/0" aka the dateline.
  How can I fix this?</p>
