title: Hide 'TitleBar' of RadWindow
body: <p>I am working with telerik WPF controls to create desktop appln.</p>
  
  <p>I want to make <strong>Radwindow</strong> looks like a <strong>UserControl</strong> (without min, max, close buttons and title) and later load this as a content in <strong>RadPane</strong>.</p>
  
  <p>If I create my view as <strong>UserControl</strong>, I can set that as content in <strong>RadPane</strong>.</p>
  
  <p>I can do same with <strong>RadWindow</strong> i.e. setting it as a content in <strong>RadPane</strong> but problem is I can still see Header, Close buttons</p>
  
  <p>How to hide <strong>'Title bar</strong>' of <strong>RadWindow</strong>?</p>
