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().
