  Description: 
      Determines the next best location to position a window (or dialog-box)
      that isn't explicitly positioned.  We do this by starting at
       (_cur_win_x, _cur_win_y) and gradually changing the offset until
       we find a spot that is not occupied.
       
      We do not worry about positioning a window so that it runs off the
      bottom of the screen. [This is a constraint for people with small
      VGA screens.]
      
  Input Parameters:
     (none)
  
  Output Parameters:
     pi_X - The next X position
     pi_Y - The next Y position
