       inserts it as the child of the specified parent.  The window is placed in the stacking order on top with respect to sibling windows.

       After reparenting the specified window, causes the X server to generate a event.  The override_redirect member returned in this event is
       set to the window's corresponding attribute.  Window manager clients usually should ignore this window if this member is set to Finally, if
       the specified window was originally mapped, the X server automatically performs a request on it.

       The X server performs normal exposure processing on formerly obscured windows.  The X server might not generate events for regions from the
       initial request that are immediately obscured by the final request.  A error results if:

       o    The new parent window is not on the same screen as the old parent window.

       o    The new parent window is the specified window or an inferior of the specified window.
