+ * Flag values for TkWindow (and Tk_FakeWin) structures are:

+ * TK_MAPPED: 1 means window is currently mapped,
+ * 0 means unmapped.
+ * TK_TOP_LEVEL: 1 means this is a top-level widget.
+ * TK_ALREADY_DEAD: 1 means the window is in the process of
+ * being destroyed already.
+ * 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.
+ * TK_ANONYMOUS_WINDOW: 1 means that this window has no name, and is
+ * thus not accessible from Tk.
+ * TK_HAS_WRAPPER 1 means that this window has a wrapper window
+ * TK_WIN_MANAGED 1 means that this window is a child of the
+ * root window, and is managed by the window
+ * manager.
+ * TK_TOP_HIERARCHY 1 means this window is at the top of a
+ * physical window hierarchy within this
+ * process, i.e. the window's parent
+ * either doesn't exist or is not owned by
+ * this Tk application.
+ * TK_PROP_PROPCHANGE 1 means that PropertyNotify events in
+ * this window's children should propagate
+ * up to this window.
