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

* 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.
