title: Fix width label with dynamic font size
body: <p>Is there a way in cascades to get font size for a given text and fixed width?</p>
  
  <p>I was trying with:</p>
  
  <pre class="lang-js prettyprint-override"><code>TextField{
    autoFit: TextAutoFit.FitToBounds
  }
  </code></pre>
  
  <p>But the text always appear left align. The requirement is to center align text with variable font size label render in fixed rect.</p>
