title: WPF Workaround to add Window control as a child of visual
body: <p>I have a requirement to add a Window control inside a panel.</p>
  
  <p>Of course this doesn't seem possible:
  Window must be the root of the tree. Cannot add Window as a child of Visual.</p>
  
  <p>The problem boils down to drawing the Window Chrome (control box, title bar, minimize/restore/close button and borders) inside a panel using the OS theme configured by the user. Are there any workarounds I should be investigating?</p>
