title: Is there a tool to convert SVG line paths from absolute to relative?
body: <p>Looking for a tool to convert something like</p>
  <pre><code>M10 20L0 0 5 5 10 10
  </code></pre>
  <p>from the absolute position to relative, something like:</p>
  <pre><code>M10 20l-10 -20 5 5 5 5
  </code></pre>
  <p>Notice the uppercase <code>L</code> for absolute and lowercase <code>l</code> for relative?</p>
