* clutter/clutter-behaviour-path.h: * clutter/clutter-behaviour-path.c: Add a "knot-reached" signal, which is emitted when the path reaches a node in the nodes list; flesh out the documentation a bit; sync the parameters names so that gtk-doc doesn't complain about missing stuff. * clutter/clutter-behaviour.h: * clutter/clutter-behaviour.c: Add the alpha value to the ClutterBehaviour::alpha_notify vfunc, so you don't have to get the value from the alpha inside the behaviour implementations; add more documentation. * clutter/clutter-alpha.c: Flesh out the description. * clutter/clutter-actor.h: Update the header. * clutter/clutter-behaviour-opacity.c: * clutter/clutter-behaviour-scale.c: Update docs.
