* gtk/gtkstyle.[ch]: Export insertion cursor drawing functionality
        in a simplified form as gtk_draw_insertion_cursor().
        (#99031, request from Alex Larsson)

        * gtk/gtktextdisplay.c gtk/gtkentry.c gtk/gtklabel.c:
        Adapt to new gtk_draw_insertion_cursor().

        * gtk/gtkradiomenuitem.c (gtk_radio_menu_item_class_init)
        gtk/gtkstyle.c (gtk_style_class_init): Add some missed
        Since: 2.4.

        * gtk/gtkiconfactory.c (icon_size_settings_changed)
          gtk/gtkicontheme.c (do_theme_change)
          gtk/gtkrc.c (_gtk_rc_context_get_default_font_name)
        * gtk/gtksettings.c (gtk_settings_notify):
        _gtk_rc_reset_styles => gtk_rc_reset_styles.
