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

 * TK_TOP_LEVEL:		1 means this is a top-level window (it
 *				was or will be created as a child of
 *				a root window).
 * 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.
