+ * e.g. center dialogs. Also, if you set the transient parent of

+ * will often center the dialog over its parent window. It's
+ * much preferred to let the window manager handle these
+ * things rather than doing it yourself, because all apps will
+ * behave consistently and according to user prefs if the window
+ * manager handles it. Also, the window manager can take the size
+ * of the window decorations/border into account, while your
+ * application cannot.
+ *
+ * In any case, if you insist on application-specified window

+ * @window: a #GtkWindow
+ * @root_x: return location for X coordinate of gravity-determined reference p\oint
+ * @root_y: return location for Y coordinate of gravity-determined reference p\oint
+ *
+ * This function returns the position you need to pass to
+ * gtk_window_move() to keep @window in its current position. This
+ * means that the meaning of the returned value varies with window
+ * gravity. See gtk_window_move() for more details.
+ *
+ * If you haven't changed the window gravity, its gravity will be
+ * #GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position()
+ * gets the position of the top-left corner of the window manager
+ * frame for the window. gtk_window_move() sets the position of this
+ * same top-left corner.
+ *
+ * gtk_window_get_position() is not 100% reliable because the X Window System
+ * does not specify a way to obtain the geometry of the
+ * decorations placed on a window by the window manager.
+ * Thus GTK+ is using a "best guess" that works with most
+ * window managers.
+ *
+ * Moreover, nearly all window managers are historically broken with
+ * respect to their handling of window gravity. So moving a window to
+ * its current position as returned by gtk_window_get_position() tends
+ * to result in moving the window slightly. Window managers are
+ * slowly getting better over time.
+ *
+ * If a window has gravity #GDK_GRAVITY_STATIC the window manager
+ * frame is not relevant, and thus gtk_window_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.
+ *
+ * If you are saving and restoring your application's window
+ * positions, you should know that it's impossible for applications to
+ * do this without getting it somewhat wrong because applications do
+ * not have sufficient knowledge of window manager state. The Correct
+ * Mechanism is to support the session management protocol (see the
+ * "GnomeClient" object in the GNOME libraries for example) and allow
+ * the window manager to save your window sizes and positions.

+ * ====================
+ *
+ * POS_CENTER_ALWAYS is conceptually a constraint rather than
+ * a default. The other POS_ values are used only when the
+ * window is shown, not after that.
+ *
+ * However, we can't implement a position constraint as
+ * "anytime the window size changes, center the window"
+ * because this may well end up fighting the WM or user. In
+ * fact it gets in an infinite loop with at least one WM.
+ *
+ * Basically, applications are in no way in a position to
+ * constrain the position of a window, with one exception:
+ * override redirect windows. (Really the intended purpose
+ * of CENTER_ALWAYS anyhow, I would think.)
+ *
+ * So the way we implement this "constraint" is to say that when WE
+ * cause a move or resize, i.e. we make a configure request changing
+ * window size, we recompute the CENTER_ALWAYS position to reflect
+ * the new window size, and include it in our request. Also, if we
+ * just turned on CENTER_ALWAYS we snap to center with a new
+ * request. Otherwise, if we are just NOTIFIED of a move or resize
+ * done by someone else e.g. the window manager, we do NOT send a
+ * new configure request.
+ *
+ * For override redirect windows, this works fine; all window
+ * sizes are from our configure requests. For managed windows,
+ * it is at least semi-sane, though who knows what the
+ * app author is thinking.
