 * TK_NEED_CONFIG_NOTIFY:     1 means that the window has been reconfigured
 *                      before it was made to exist.  At the time of
 *                      making it exist a ConfigureNotify event needs
 *                      to be generated.
 * TK_GRAB_FLAG:        Used to manage grabs.  See tkGrab.c for
 *                      details.
 * TK_CHECKED_IC:       1 means we've already tried to get an input
 *                      context for this window;  if the ic field
 *                      is NULL it means that there isn't a context
 *                      for the field.
 * TK_DONT_DESTROY_WINDOW:    1 means that Tk_DestroyWindow should not
 *                      invoke XDestroyWindow to destroy this widget's
 *                      X window.  The flag is set when the window
 *                      has already been destroyed elsewhere (e.g.
 *                      by another application) or when it will be
 *                      destroyed later (e.g. by destroying its
 *                      parent).
 * TK_WM_COLORMAP_WINDOW:     1 means that this window has at some time
 *                      appeared in the WM_COLORMAP_WINDOWS property
 *                      for its toplevel, so we have to remove it
 *                      from that property if the window is
 *                      deleted and the toplevel isn't.
 * TK_EMBEDDED:               1 means that this window (which must be a
 *                      toplevel) is not a free-standing window but
 *                      rather is embedded in some other application.
 * TK_CONTAINER:        1 means that this window is a container, and
 *                      that some other application (either in
 *                      this process or elsewhere) may be
 *                      embedding itself inside the window.
 * TK_BOTH_HALVES:            1 means that this window is used for
 *                      application embedding (either as
 *                      container or embedded application), and
 *                      both the containing and embedded halves
 *                      are associated with windows in this
 *                      particular process.
 * TK_DEFER_MODAL:            1 means that this window has deferred a modal
 *                      loop until all of the bindings for the current
 *                      event have been invoked.
 * TK_WRAPPER:                1 means that this window is the extra
 *                      wrapper window created around a toplevel
 *                      to hold the menubar under Unix.  See
 *                      tkUnixWm.c for more information.
 * TK_REPARENTED:       1 means that this window has been reparented
 *                      so that as far as the window system is
 *                      concerned it isn't a child of its Tk
 *                      parent.  Initially this is used only for
 *                      special Unix menubar windows.
