I have a rather unusual question: does anyone know if it is possible to draw something on the back of a WPF window?
Typically, people create controls or draw images on the front of a WPF window. However, I would like to draw things on the back. Here is an image taken with Snoop . Snoop has the functionality of viewing a WPF application in 3D. Using the so-called Zoomer , you can look out the window. 
I would like to either draw an image or put a control so that you can see it using the Zoomer snoop function on the back of the application.
Has anyone understood how this can be done?
Thanks Christian
