title: Convert pack:// URI to relative URI
body: <p>During serialization with a <code>XamlWriter</code>, among other things I am trying to serialize <code>Image</code> controls. These <code>Source</code> property of these controls is set to a relative URI.</p>
  
  <p>However, after serializing with the <code>XamlWriter</code>, the <code>Image</code> controls contain paths like this:</p>
  
  <p><b>Original Path</b></p>
  
  <pre><code>../test.png
  </code></pre>
  
  <p><b>XamlWriter Path</b></p>
  
  <pre><code>pack://application:,,,/test.png
  </code></pre>
  
  <p>Is there any way to prevent the <code>XamlWriter</code> from changing relative paths to pack paths?</p>
