title: Inner shadow issue
body: <p>I have this code to realize <strong>the inner shadow.</strong></p>
  
  <p>Somehow it includes the <code>TextBlock</code> and etc. I don't need it. I need <em>ONLY INNER SHADOW</em>.</p>
  
  <p>It is near the problem described <a href="https://stackoverflow.com/questions/2831062/wpf-drop-shadow">here</a> but I have the inner shadow...</p>
  
  <p>So I want to keep the inner shadow but don't apply it to fonts and etc.</p>
  
  <p>Please help me to fix it. Thank you!</p>
