Bug 1014 - Clutter Animation API Improvements

	* clutter/Makefile.am:
	* clutter/clutter.h: Update the build

	* clutter/clutter-types.h: Add AnimationMode, an enumeration
	for easing functions.

	* clutter/clutter-alpha.[ch]: Add the :mode property to
	control the function bound to an Alpha instance using an
	enumeration value. Also add six new alpha functions:

		- ease-in, ease-out, ease-in-out
		- sine-in, sine-out, sine-in-out

	* clutter/clutter-deprecated.h: Deprecate the #defines for
	the alpha functions. They will be replaced by entries in the
	ClutterAnimationMode.

	* clutter/clutter-interval.[ch]: Add ClutterInterval, an
	object for defining, validating and computing an interval
	between two values.

	* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
	object responsible for animation the properties of a single
	actor along an interval of values. ClutterAnimation memory
	management is automatic. A simple wrapper method for
	ClutterActor is provided:

		clutter_actor_animate()

	which will create, or update, an animation for the passed
	actor.

	* clutter/clutter-debug.h:
	* clutter/clutter-main.c: Add a new 'animation' debug note.

	* clutter/clutter-script.c: Clean up the alpha functions
	whitelist, and add the new functions.

	* doc/reference/clutter/Makefile.am:
	* doc/reference/clutter/clutter-sections.txt: Update the
	API reference.

	* doc/reference/clutter/clutter-animation.xml: Renamed to
	doc/reference/clutter/clutter-animation-tutorial.xml to
	avoid clashes with the ClutterAnimation section.

	* doc/reference/clutter/clutter-docs.sgml: Renamed to
	doc/reference/clutter/clutter-docs.xml, as it was an XML
	file and not a SGML file.

	* tests/Makefile.am:
	* tests/interactive/Makefile.am:
	* tests/interactive/test-animation.c:
	* tests/interactive/test-easing.c: Add two tests for the
	new simple animation API and the easing functions.

	* tests/interactive/test-actors.c:
	* tests/interactive/test-behave.c:
	* tests/interactive/test-depth.c:
	* tests/interactive/test-effects.c:
	* tests/interactive/test-layout.c:
	* tests/interactive/test-multistage.c:
	* tests/interactive/test-paint-wrapper.c:
	* tests/interactive/test-rotate.c:
	* tests/interactive/test-scale.c:
	* tests/interactive/test-texture-quality.c:
	* tests/interactive/test-threads.c:
	* tests/interactive/test-viewport.c: Update interactive tests
	to the deprecations and new alpha API.

/**
* SECTION:clutter-interval
* @short_description: An object holding an interval of two values
*
* #ClutterInterval is a simple object that can hold two values
* defining an interval. #ClutterInterval can hold any value that
* can be enclosed inside a #GValue.
*
* Once a #ClutterInterval for a specific #GType has been instantiated
* the #ClutterInterval:value-type property cannot be changed anymore.
*
* #ClutterInterval starts with a floating reference; this means that
* any object taking a reference on a #ClutterInterval instance should
* also take ownership of the interval by using g_object_ref_sink().
*
* #ClutterInterval is used by #ClutterAnimation to define the
* interval of values that an implicit animation should tween over.
*
* #ClutterInterval can be subclassed to override the validation
* and value computation.
*
* #ClutterInterval is available since Clutter 1.0

<title>Implicit Animations</title>
<para>Using behaviours for simple animations of a single actor may
be too complicated, in terms of memory management and bookkeeping
of the object instances. For this reason, Clutter also provides a
simple animation API for implicit animations using properties of
an actor: clutter_actor_animate().</para>
<para>The clutter_actor_animate() family of functions will create
and use an implicit #ClutterAnimation instance, which will then
handle the animation of one or more #ClutterActor properties between
a range of values.</para>
<example id="clutter-actor-animate-example">
<para>
Clutter effects API provide a simplified abstraction for firing simple
transitions from code. Clutter effects are created from a
#ClutterEffectTemplate which is an abstraction of a timeline and
an alpha function. An effect template can be created with:
The following example demonstrates how to use the
clutter_actor_animate() method to tween an actor
between the current position and a new set of coordinates.
The animation takes 200 milliseconds to complete and
uses a linear speed.
</para>
<programlisting>
ClutterEffectTemplate *etemplate =
clutter_effect_template_new_for_duration (2000, CLUTTER_ALPHA_RAMP_INC);
clutter_actor_animate (actor, CLUTTER_LINEAR, 200
"x", 200,
"y", 200,
NULL);
</programlisting>
</example>
<para>The clutter_actor_animate() method returns a #ClutterAnimation
instance that can be used to start, stop and modify the animation
while it's running. The #ClutterAnimation::completed signal will
be emitted when the animation has been completed.</para>
<warning><para>When the animation is complete it will be automatically
unreferenced, and disposed if nothing else is holding a reference
on it.</para></warning>
<para>Calling clutter_actor_animate() multiple times on an
actor which is being animated will cause the animation to be updated
with the new values.</para>
<example id="clutter-actor-animate-multi-example">
<para>
This will create an effect template lasting 2000 milliseconds (2
seconds) and use an alpha function of %CLUTTER_ALPHA_RAMP_INC, there
are other more advanced forms for creating effect templates from
existing timelines, as well as attaching a callback to be called
with user_data when the effect template is destroyed.
</para>
<para>
When we have an effect template we can create a temporary behaviour
animating an actor simply by issuing:
The following example demonstrates how to animate an actor
inside the signal handler for a button press event. If the
user presses the button on a new position while the animation
is running, the animation will be restarted with the new
final values updated.
</para>
<programlisting>
clutter_effect_move (etemplate, actor, 23, 42, NULL, NULL);
static gboolean
on_button_press (ClutterActor *actor,
ClutterButtonEvent *event,
gpointer user_data)
{
clutter_actor_animate (actor, CLUTTER_SINE_IN_OUT, 500,
"x", event-&gt;x,
"y", event-&gt;y,
NULL);
return TRUE;
}
</programlisting>
<para>
and the actor will move from its current position to the coordinates
(23, 42) in 2 seconds. Effects can also be stacked, so calling:
</para>
<programlisting>
clutter_effect_move (etemplate, actor, 23, 42, NULL, NULL);
clutter_effect_fade (etemplate, actor, 0, NULL, NULL);
</programlisting>
<para>
The actor will move and fade out at the same time.
</para>
<para>
</example>
Since effects return a #ClutterTimeline, you can stop an effect from
immediatly happening by calling clutter_timeline_stop () on the
returned timeline.
</para>
<para>
The timeline and all the effect infrastructure is unreferenced as soon
as the timeline emits the ClutterTimeline::completed signal.

Of course animations can be created outside of Clutter Utilities,
they are not expected to cover every kind of possible animation
scenario.
