        * gtk/gtkclist.c (gtk_clist_row_from_ypixel): removed this function,
                it was unneeded and not exported.

                        * gtk/gtkwidget.c (gtk_widget_ref) (gtk_widget_unref): don't check-cast
                                the widgets to volatile GtkObjects (which was there for debugging
                                        purposes only). these functions should probably be macros, but that
                                                would break binary compatibility again, sigh.
                                                        (gtk_widget_destroy): removed superfluous check-casts, since the
                                                                neccessary checks are done in gtk_object_destroy anyways. this should
                                                                        be a macro as well but stays as a function for the above reasoonings.
