   * size (but this is not reliably the same as the size the window manager
   * will actually select). See: set_default_size().
   * 
   * Depending on the windowing system and the window manager constraints,
   * the size returned by this function may not match the size set using
   * resize(); additionally, since resize() may be
   * implemented as an asynchronous operation, GTK+ cannot guarantee in any
   * way that this code:
   * 
   * 
   * [C example ellipted]
   * 
   * will result in `new_width` and `new_height` matching `width` and
   * `height`, respectively.
   * 
   * This function will return the logical size of the Gtk::Window,
   * excluding the widgets used in client side decorations; there is,
   * however, no guarantee that the result will be completely accurate
   * because client side decoration may include widgets that depend on
   * the user preferences and that may not be visibile at the time you
   * call this function.
   * 
   * The dimensions returned by this function are suitable for being
   * stored across sessions; use set_default_size() to
   * restore them when before showing the window.
   * 
   * To avoid potential race conditions, you should only call this
   * function in response to a size change notification, for instance
   * inside a handler for the Gtk::Widget::signal_size_allocate() signal, or
   * inside a handler for the Gtk::Widget::signal_configure_event() signal:
   * 
   * 
   * [C example ellipted]
   * 
   * Note that, if you connect to the Gtk::Widget::signal_size_allocate() signal,
   * you should not use the dimensions of the Gtk::Allocation passed to
   * the signal handler, as the allocation may contain client side
   * decorations added by GTK+, depending on the windowing system in
   * use.
   * 
   * If you are getting a window size in order to position the window
   * on the screen, you should, instead, simply set the window’s semantic
   * type with set_type_hint(), which allows the window manager
   * to e.g. center dialogs. Also, if you set the transient parent of
   * dialogs with set_transient_for() window managers will
   * often center the dialog over its parent window. It's much preferred
   * to let the window manager handle these cases rather than doing it
   * yourself, because all apps will behave consistently and according to
   * user or system preferences, if the window manager handles it. Also,
   * the window manager can take into account the size of the window
   * decorations and border that it may add, and of which GTK+ has no
   * knowledge. Additionally, positioning windows in global screen coordinates
   * may not be allowed by the windowing system. For more information,
   * see: set_position().
   * 
   * @param width Return location for width.
   * @param height Return location for height.

  /** Asks the [window manager][gtk-X11-arch] to move
   *  @a window to the given position.  %Window managers are free to ignore
   * this; most window managers ignore requests for initial window
   * positions (instead using a user-defined placement algorithm) and
   * honor requests after the window has already been shown.
   * 
   * @note the position is the position of the gravity-determined
   * reference point for the window. The gravity determines two things:
   * first, the location of the reference point in root window
   * coordinates; and second, which point on the window is positioned at
   * the reference point.
   * 
   * By default the gravity is Gdk::GRAVITY_NORTH_WEST, so the reference
   * point is simply the @a x, @a y supplied to move(). The
   * top-left corner of the window decorations (aka window frame or
   * border) will be placed at @a x, @a y.  Therefore, to position a window
   * at the top left of the screen, you want to use the default gravity
   * (which is Gdk::GRAVITY_NORTH_WEST) and move the window to 0,0.
   * 
   * To position a window at the bottom right corner of the screen, you
   * would set Gdk::GRAVITY_SOUTH_EAST, which means that the reference
   * point is at @a x + the window width and @a y + the window height, and
   * the bottom-right corner of the window border will be placed at that
   * reference point. So, to place a window in the bottom right corner
   * you would first set gravity to south east, then write:
   * `gtk_window_move (window, gdk_screen_width() - window_width,
   * gdk_screen_height() - window_height)` (note that this
   * example does not take multi-head scenarios into account).
   * 
   * The [Extended Window Manager Hints Specification](http://www.freedesktop.org/Standards/wm-spec)
   * has a nice table of gravities in the “implementation notes” section.
   * 
   * The get_position() documentation may also be relevant.
   * 
   * @param x X coordinate to move window to.
   * @param y Y coordinate to move window to.
   */
  void move(int x, int y);

  
  /** This function returns the position you need to pass to
   * move() to keep @a window in its current position.
   * This means that the meaning of the returned value varies with
   * window gravity. See move() for more details.
   * 
   * The reliability of this function depends on the windowing system
   * currently in use. Some windowing systems, such as Wayland, do not
   * support a global coordinate system, and thus the position of the
   * window will always be (0, 0). Others, like X11, do not have a reliable
   * way to obtain the geometry of the decorations of a window if they are
   * provided by the window manager. Additionally, on X11, window manager
   * have been known to mismanage window gravity, which result in windows
   * moving even if you use the coordinates of the current position as
   * returned by this function.
   * 
   * If you haven’t changed the window gravity, its gravity will be
   * Gdk::GRAVITY_NORTH_WEST. This means that get_position()
   * gets the position of the top-left corner of the window manager
   * frame for the window. move() sets the position of this
   * same top-left corner.
   * 
   * If a window has gravity Gdk::GRAVITY_STATIC the window manager
   * frame is not relevant, and thus get_position() will
   * always produce accurate results. However you can’t use static
   * gravity to do things like place a window in a corner of the screen,
   * because static gravity ignores the window manager decorations.
   * 
   * Ideally, this function should return appropriate values if the
   * window has client side decorations, assuming that the windowing
   * system supports global coordinates.
   * 
   * In practice, saving the window position should not be left to
   * applications, as they lack enough knowledge of the windowing
   * system and the window manager state to effectively do so. The
   * appropriate way to implement saving the window position is to
   * use a platform-specific protocol, wherever that is available.

   * @param root_x Return location for X coordinate of gravity-determined reference point.
