Original commit message from CVS: * libs/gst/controller/gstcontroller.c: * libs/gst/controller/gstcontrollerprivate.h: Keep last-value and only call set_property if value has changed. This supresses all the g_object_notifies we would trigger otherwise. It also allows the user to chage the value while there is no controller change.
