    FUNCTION
        This routine sends a request to Intuition asking to send the window
        in back of all other windows in the screen.
        Note that the window will not be depth-arranged immediately, but rather
        will be arranged the next time Intuition receives an input event,
        which happens currently at a minimum rate of ten times per second,
        and a maximum of sixty times a second.
        remember that wflg_backdrop windows cannot be depth-arranged.
