 801  * Flag values for TkWindow (and Tk_FakeWin) structures are:
 802  *
 803  * TK_MAPPED:                   1 means window is currently mapped,
 804  *                              0 means unmapped.
 805  * TK_TOP_LEVEL:                1 means this is a top-level widget.
 806  * TK_ALREADY_DEAD:             1 means the window is in the process of
 807  *                              being destroyed already.
 808  * TK_NEED_CONFIG_NOTIFY:       1 means that the window has been reconfigured
 809  *                              before it was made to exist.  At the time of
 810  *                              making it exist a ConfigureNotify event needs
 811  *                              to be generated.
 812  * TK_GRAB_FLAG:                Used to manage grabs.  See tkGrab.c for
 813  *                              details.
 814  * TK_CHECKED_IC:               1 means we've already tried to get an input
 815  *                              context for this window;  if the ic field
 816  *                              is NULL it means that there isn't a context
 817  *                              for the field.
 818  * TK_DONT_DESTROY_WINDOW:      1 means that Tk_DestroyWindow should not
 819  *                              invoke XDestroyWindow to destroy this widget's
 820  *                              X window.  The flag is set when the window
 821  *                              has already been destroyed elsewhere (e.g.
 822  *                              by another application) or when it will be
 823  *                              destroyed later (e.g. by destroying its
 824  *                              parent).
 825  * TK_WM_COLORMAP_WINDOW:       1 means that this window has at some time
 826  *                              appeared in the WM_COLORMAP_WINDOWS property
 827  *                              for its toplevel, so we have to remove it
 828  *                              from that property if the window is
 829  *                              deleted and the toplevel isn't.
 830  * TK_EMBEDDED:                 1 means that this window (which must be a
 831  *                              toplevel) is not a free-standing window but
 832  *                              rather is embedded in some other application.
 833  * TK_CONTAINER:                1 means that this window is a container, and
 834  *                              that some other application (either in
 835  *                              this process or elsewhere) may be
 836  *                              embedding itself inside the window.
 837  * TK_BOTH_HALVES:              1 means that this window is used for
 838  *                              application embedding (either as
 839  *                              container or embedded application), and
 840  *                              both the containing and embedded halves
 841  *                              are associated with windows in this
 842  *                              particular process.
 843  * TK_DEFER_MODAL:              1 means that this window has deferred a modal
 844  *                              loop until all of the bindings for the current
 845  *                              event have been invoked.
 846  * TK_WRAPPER:                  1 means that this window is the extra
 847  *                              wrapper window created around a toplevel
 848  *                              to hold the menubar under Unix.  See
 849  *                              tkUnixWm.c for more information.
 850  * TK_REPARENTED:               1 means that this window has been reparented
 851  *                              so that as far as the window system is
 852  *                              concerned it isn't a child of its Tk
 853  *                              parent.  Initially this is used only for
 854  *                              special Unix menubar windows.
 855  * TK_ANONYMOUS_WINDOW:         1 means that this window has no name, and is
 856  *                              thus not accessible from Tk.
 857  * TK_HAS_WRAPPER               1 means that this window has a wrapper window
 858  * TK_WIN_MANAGED               1 means that this window is a child of the
 859  *                              root window, and is managed by the window
 860  *                              manager.
 861  * TK_TOP_HIERARCHY             1 means this window is at the top of a
 862  *                              physical window hierarchy within this
 863  *                              process, i.e. the window's parent
 864  *                              either doesn't exist or is not owned by
 865  *                              this Tk application.
 866  * TK_PROP_PROPCHANGE           1 means that PropertyNotify events in
 867  *                              this window's children should propagate
 868  *                              up to this window.
