docs: Like xdo_get_focused_window, but return the first ancestor-or-self
          window * having a property of WM_CLASS. This allows you to get
          the "real" or top-level-ish window having focus rather than something
          you may not expect to be the window having focused.
  
          :param window_ret:
              Pointer to a window where the currently-focused window
              will be stored.
