title: Combine <use>-tags or make <path> out of <use>-tags
body: <p><em>Using SVG via Inkscape:</em></p>
  
  <p>I have several <code>&lt;use&gt;</code>-tags, which are reusing the same <code>&lt;line&gt;</code> (from the defs), while transforming it.</p>
  
  <p>Now I want to create a shape (<code>&lt;path&gt;</code>) by combining some "transformed lines" and connecting the end-points. Inkscape has a tool to combine paths, but it seems to me that is not possible to combine several use-tags.</p>
  
  <p>How can I create a separate path from a <code>&lt;use&gt;</code>-tag, to later combine them into one path?</p>
  
  <p>simplified example:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt;
  &lt;svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"&gt;
      &lt;defs&gt;
          &lt;symbol id="extended_segment"&gt;
              &lt;line style="stroke:#000000;" y2="240" x2="615" y1="240" x1="240"/&gt;
          &lt;/symbol&gt;
      &lt;/defs&gt;
      &lt;use xlink:href="#extended_segment" transform="matrix(0,-1,1,0,330,615)" /&gt;
      &lt;use xlink:href="#extended_segment" transform="matrix(0.5,-0.8660254,0.8660254,0.5,242.1539,462.8461)" /&gt;
  &lt;/svg&gt;
  </code></pre>
  
  <p>This example should result in a triangle-shaped path…</p>
