Tim Janik 238ede333f changed scrolled window inheritance, it inherits from GtkBin now. 
Sat Nov 28 03:13:42 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkscrolledwindow.h:
        * gtk/gtkscrolledwindow.c: changed scrolled window inheritance,
        it inherits from GtkBin now.

        * gtk/gtkbin.c (gtk_bin_unmap): removed superfluous check for
        visibility of child.
        (gtk_bin_draw): removed superfluous check for GTK_WIDGET_DRAWABLE().
        added check so a child gets only drawn if it's visible.

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c: removed gtk_widget_draw_children().

        * gtk/gtkstyle.h:
        * gtk/gtkstyle.c: rmoved gtk_reset_widget_shapes.

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c: removed crufty relict: gtk_widget_is_child().
        added internal function gtk_widget_reset_shapes() from gtkstyle.c.

        * gtk/gtkrc.h:
        * gtk/gtkrc.c: (gtk_rc_find_pixmap_in_path): removed bogus gscanner
        argument, changed callers.

        * gtk/gtkmenufactory.c: GtkMenuFactory is deprecated for a long time,
        it will issue a warning now.

        * gtk/gtkcompat.h: new file to #define aliases for historic
        function names.

        * changed 8 function names for consistency and provided aliases to keep
        source compatibility in gtkcompat.h:
        (gtk_accel_label_get_accel_width): renamed from gtk_accel_label_accelerator_width
        (gtk_container_set_border_width): renamed from gtk_container_border_width
        (gtk_notebook_get_current_page): renamed from gtk_notebook_current_page
        (gtk_packer_configure): renamed from gtk_packer_set_child_packing
        (gtk_paned_set_gutter_size): renamed from gtk_paned_gutter_size
        (gtk_paned_set_handle_size): renamed from gtk_paned_handle_size
        (gtk_scale_get_value_width): renamed from gtk_scale_value_width
        (gtk_window_set_position): renamed from gtk_window_position

        * renamed a few recently added funtions for consistency:
        (gtk_notebook_get_tab_label): renamed from gtk_notebook_query_tab_label.
        (gtk_notebook_get_menu_label): renamed from gtk_notebook_query_menu_label.
        (gtk_progress_configure): renamed from gtk_progress_reconfigure.
