title: FB.ui and setting popup size
body: <p>I am using FB.ui with the display parameter set to popup. </p>
  
  <p>When the method is 'stream.publish', it autoresizes when the content is loaded. However, when using 'fbml.dialog' (in order to display a multi-friend selector) it shows a size that I'm not able to change (and the content is displayed cropped).</p>
  
  <p>I have tried with the following approaches, with no luck:</p>
  
  <pre><code>FB.ui({
  method: 'fbml.dialog',
  size: {width: 800, height: 500},
  ...
  
  FB.ui({
  method: 'fbml.dialog',
  width: 800,
  height: 500,
  ...
  </code></pre>
  
  <p>Also I've been looking at the API source code, and it declares the method this way:</p>
  
  <p>Method declaration:</p>
  
  <pre><code>'fbml.dialog': {
      size : { width: 575, height: 300 },
      url : 'render_fbml.php',
      loggedOutIframe : true
  }...
  </code></pre>
  
  <p>Functions that executes the methods:</p>
  
  <pre><code>// the basic call data
  var call = {
    cb : cb,
    id : id,
    size : method.size || {},
    url : FB._domain.www + method.url,
    params : params
  };
  </code></pre>
  
  <p>Any help would be much appreciated...</p>
