171a7647b9 Bug 1395 - apply and get_nth_actor are inconsistent
When calling clutter_behaviour_apply() the new actor is prepended
to the list of actors to which a behaviour is applied; this breaks
the rest of methods working on the actors list, e.g.:

  # adding actors
  apply(actor_0);
  apply(actor_1);
  apply(actor_2);

  # expected: [ actor_0, actor_1, actor_2 ]
  [ actor_2, actor_1, actor_0 ] = get_actors();

  # expected: actor_2
  actor_0 = get_nth_actor(2);

This commit fixes the inconsistency in the returned values.

7d7372af43 [animation] Move the alpha value to floating point
The current Alpha value is an unsigned integer that can be used
implicitly as a fixed point value. This makes writing an alpha
function overshooting below and above the current range basically
impossible without complicating an already complex code, and
creating weird corner cases.

For this reason, the Alpha value should be defined as a floating
point normalized value, spanning a range between 0.0 and 1.0; in
order to allow overshooting, the valid range is extended one unit
below and one unit above, thus making it -1.0 .. 2.0.

This commit updates the various users of the ClutterAlpha API
and the tests cases.

This commit also removes all the current alpha functions exposed
in the public API.

39f4848b93 Fix some *_set functions so they work if the object is the same value
Bug 1392 - behaviour_set_alpha set same alpha twice lead to warning
and destroy the input alpha

The following functions are fixed:

clutter_actor_set_shader
clutter_alpha_set_timeline
clutter_behaviour_set_alpha
clutter_clone_texture_set_parent_texture

They either now reference the new value before destroying the old
value, or just return immediately if the values are the same.

454e493197 Fix various compiler warnings
Most of these fixes are simple symbol shadowing issues, like index and the
braindead y0 and y1 extern symbols exported by math.h on GNU libc systems.

There is a masking issue in ClutterTexture which should be checked; I ran
the tests and everything looked fine.

The rest are just unused variables.

10fbfb1659 2006-12-12 Emmanuele Bassi <ebassi@openedhand.com>
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().

* clutter/clutter-behaviour.h: Add a function prototype
	for the foreach function: we need something more specific
	than GFunc; add clutter_behaviour_get_actors(), used to
	get a list of the actors.

	* clutter/clutter-behaviour.c: Add debugging notes; add
	a warning for behaviour implementations missing the
	alpha_notify vfunc; add api documentation

	* clutter/clutter-behaviour-opacity.c:
	* clutter/clutter-behaviour-path.c:
	* clutter/clutter-behaviour-scale.c: Reimplement the
	alpha_notify functions using the new foreach function
	and, where possible, by directly iterating on the
	actors: this shaves off the number of recalculations
	of the property/alpha values, and the number of
	functions.

	* clutter/clutter-behaviour-scale.c: Add properties for

	* clutter/clutter-behaviour-path.h: Mark the ClutterKnot
	memory management functions as public (for the bindings),
	since we use the slice allocator for copying knots around;
	add a clutter_knot_equal() function.

	* clutter/clutter-behaviour-path.c:
	(node_distance): Use clutter_knot_equal() as a fast path
	to avoid the sqrt() in case the nodes we are using are
	at the same position.
	(path_total_length): Additional check on the existence
	of the next node.

	* examples/behave.c: Do not leak the ClutterBehaviour
	objects around.
