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.
