title: SVG translate with em as unit?
body: <p>Is there a way to use em as unit for SVG translations? As in</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;rect height="10em" width="10em" transform="translate(0em, 10em)"
   style="fill:none;stroke-width:3;stroke:black/&gt;
  </code></pre>
  
  <p>The rectangle does not translate in Firefox, unless I remove the em as unit.</p>
