"""
    Demo showing how to remove the titlebar and replace with your own
    Unlike previous demos that lacked a titlebar, this one provides a way for you
    to "minimize" your window that does not have a titlebar.  This is done by faking
    the window using a hidden window that is minimized.
   
    The DarkGrey8 is already a theme in PySimpleGUI.  It's here to show you how to add your own and have it them
    be used by your Custom Titlebar.
