6.19.2 Panel Objects 
Panel objects, as returned by new_panel() above, are windows
with a stacking order. There's always a window associated with a
panel which determines the content, while the panel methods are
responsible for the window's depth in the panel stack.
Panel objects have the following methods:
- 
Returns the panel above the current panel.
- 
Returns the panel below the current panel.
- 
Push the panel to the bottom of the stack.
- 
Returns true if the panel is hidden (not visible), false otherwise.
- 
Hide the panel. This does not delete the object, it just makes the
window on screen invisible.
- 
Move the panel to the screen coordinates (y, x).
- 
Change the window associated with the panel to the window win.
- 
Set the panel's user pointer to obj. This is used to associate an
arbitrary piece of data with the panel, and can be any Python object.
- 
Display the panel (which might have been hidden).
- 
Push panel to the top of the stack.
- 
Returns the user pointer for the panel.  This might be any Python object.
- 
Returns the window object associated with the panel.
