Wed Jun 24 16:38:02 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkbin.c (gtk_bin_remove): do not avoid to queue for a resize
        if the container is not visible, we might be a toplevel! this holds
        for all other base container implementations as well, that are
        candidates to derive toplevels from. in general the resizing code will
        care about visibility itself.
        * gtk/gtkmenushell.c (gtk_menu_shell_remove): likewise.
        * gtk/gtkbox.c (gtk_box_remove): likewise.

        * gtk/gtkwindow.c (gtk_window_move_resize): save ->use_uposition around
        gtk_window_set_hints(), since we haven't calculated the new position
        yet.

        * gdk/gdkwindow.c (gdk_window_get_pointer): take care that *x, *y and
        *mask are alway initialized in a sane way, regardless of the return
        value.
