Rework part of the show/hide machinery.  Allow groups sub-classes
	and composite actors to override show_all/hide_all in order to
	decide which children they wish to show/hide.  This means that
	if an actor overrides the default show/hide virtual methods, it'll
	have to chain up to the parent class show/hide.  While we're at it,
	provide the fully recursive clutter_actor_show_all() and
	clutter_actor_hide_all() methods.

	* clutter/clutter-behaviour-path.c: Add apidoc for the ClutterKnot
	functions; add pathological equality case for clutter_knot_equal().

	* clutter/clutter-event.h:
	* clutter/clutter-feature.h:
	* clutter/clutter-behaviour.c:
	* clutter/clutter-behaviour-scale.c:Fix parameters name so that
	gtk-doc doesn't complain.

	* clutter/clutter-actor.c:
	* clutter/clutter-event.c: Add apidoc

	* clutter/clutter-actor.h:
	* clutter/clutter-actor.c: Add a clutter_actor_show_all() and a
	clutter_actor_hide_all() functions; provide a mechanism for
	groups and composited actors to programmatically select what to
	show/hide when clutter_actor_show_all() and clutter_actor_hide_all()
	are called.  If you are overriding the ClutterActor::show or
	the ClutterActor::hide virtual methods you should chain up with
	the parent class.

	* clutter/clutter-group.c: Override show_all and hide_all and
	recursively show/hide every child inside the group;
	clutter_group_show_all() and clutter_group_hide_all() remain as non
	recursive versions of clutter_actor_show_all() and
	clutter_actor_hide_all() (maybe we should rename them in order
	to avoid name clashes with the bindings).

	* clutter/clutter-stage.c:
	* clutter/clutter-texture.c: Chain up with parent class show
	and hide vfuncs.

	* clutter/clutter-clone-texture.h:
	* clutter/clutter-clone-texture.c: Provide API for changing the
	parent texture of a clone texture actor.

	* examples/behave.c:
	* examples/super-oh.c:
	* examples/test.c: Use clutter_actor_show_all() instead of
	clutter_group_show_all().
