add new signal 'adjust_bounds' to potentialy change the bounds before
2002-02-14 Jody Goldberg <jody@gnome.org>
* gtk/gtkrange.c (gtk_range_class_init) : add new signal
'adjust_bounds' to potentialy change the bounds before assigning the
new value and camping it to the existing bounds.
(gtk_range_internal_set_value) : used here. #68800.
* gtk/gtkmarshalers.list : add VOID:DOUBLE
