title: changing font size of material-ui buttons, and having the buttons scale?
body: <p>I seem to be having an issue with changing the font sizes on Material-UI's (for React) RaisedButton and having the button itself scale properly with it.</p>
  
  <pre><code>&lt;RaisedButton
  label={&lt;span className="buttonText"&gt;Log in Here&lt;/span&gt;}
  /&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre><code>.buttonText {
      font-size: 63px;
  }
  </code></pre>
  
  <p>The text size changes but the button itself doesn't scale with it. Does anyone know the proper solution to this? I want to button to scale with the text size.</p>
