title: Make SVG Image ignore parent viewBox
body: <p>I have image inside svg with viewBox, is it possible to make image ignore scaling caused by viewBox and always keep size image 50x50?</p>
  
  <pre><code>&lt;svg xmlns="http://www.w3.org/2000/svg" width="500" height="500" viewBox="0 0 200 200" preserveAspectRatio="xMidYMid meet"&gt;
      &lt;image xlink:href="someimage.png" width="50" height="50"&gt;&lt;/image&gt;
  &lt;/svg&gt;
  </code></pre>
