title: How can I get real point position of WPF Polyline points?
body: <p>I am trying to draw some marks (red circles) over my WPF PolyLine points.</p>
  
  <p>So I can get position of each PolyLine.Point and draw my mark. </p>

  <p>And this is ok, but problem appears when Polyline <strong>Stretch</strong> is applied!</p>
  
  <p>So when <strong>Stretch</strong> is applied point coordinates not equals to real position of point on screen.</p>

  <p>Any ideas how to get real point position on screen when <strong>Stretch</strong> is applied?</p>
