  #
  # Abstract base class for all top-level windows.
  #
  # TopWindows are usually managed by a Window Manager under X11 and
  # therefore borders and window-menus and other decorations like resize-
  # handles are subject to the Window Manager's interpretation of the
  # decoration hints.
  # When a TopWindow is closed, it sends a SEL_CLOSE message to its
  # target.  The target should return 0 in response to this message if
  # there is no objection to proceed with the closing of the window, and
  # return 1 otherwise.  After the SEL_CLOSE message has been sent and
  # no objection was raised, the window will delete itself.
  # When the session is closed, the window will send a SEL_SESSION_NOTIFY
  # message to its target, allowing the application to write any unsaved
  # data to the disk.  If the target returns 0, then the system will proceed
  # to close the session.  Subsequently a SEL_SESSION_CLOSED will be received
  # which causes the window to be closed with prejudice by calling the
  # function close(FALSE).
  # When receiving a SEL_UPDATE, the target can update the title string
  # of the window, so that the title of the window reflects the name
  # of the document, for example.
  # For convenience, TopWindow provides the same layout behavior as
  # the Packer widget, as well as docking and undocking of toolbars.
  # TopWindows can be owned by other windows, or be free-floating.
  # Owned TopWindows will usually remain stacked on top of the owner
  # windows. The lifetime of an owned window should not exceed that of
  # the owner.
  #
