/**
* 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 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.
