title: JTextPane vertical alignment
body: <p>When I use a <code>JTextPane</code> I can set the horizontal alignment via HTML:</p>
  
  <pre><code>&lt;html&gt;&lt;center&gt;my text&lt;/center&gt;&lt;/html&gt;
  </code></pre>
  
  <p>However, does one of you know how I can set vertical alignment? Is it also possible with HTML?</p>
