b5af8fbfac docs: Add recipe about implementing a ClutterEffect
Add a recipe showing how to implement two simple
effects, based on ClutterEffect: an always gray background,
and a border with configurable width and color.

Also explains the necessity to queue a redraw on
the associated actor if the effect's properties change,
and shows how to implement that.

The example gives the GObject code for both effects,
as well as an example application showing how to use them.
The example also demonstrates how to disable/enable an effect,
making the border round an actor togglable.

74de3cfdf3 docs: Add effects chapter, with introduction and first recipe
Add an effects chapter which gives a broad overview of
the abstract classes in the effects API, plus a short
example of how to apply one of the stock Clutter
effects (ClutterColorizeEffect).

The recipe explains how to create a custom ClutterDeformEffect
to produce a page fold (code based on ClutterPageTurnEffect).

The example code includes the effect class plus a small
application to apply it to a texture.

cf18836ca0 docs: Add recipe for animating an actor on a curved path
Show how to animate an actor using a ClutterPathConstraint.

This demonstrates how to get effects similar to
ClutterPathBehaviour with the modern animation APIs.

Includes 3 examples:

1) Simple ClutterPathConstraint used with implicit animations
2) ClutterPathConstraint used to simulate circular animation,
using ClutterAnimator
3) Creating simple curved path animations with non-linear
easing

428f64212c build: Fixes to pass distcheck
Try to make the cookbook pass the distcheck phase, so that we can run
distcheck with --enable-docs, and make sure that a tarballed clutter
release can actually build the cookbook.

ce0bd4e26c cookbook: Recipe for "moving actors"
This recipe explains how to use the three animation
approaches (implicit, State, Animator) to animate movement
of actors.

Includes some guidelines about which approach to use when, with
a full code example for each approach.

The discussion section covers some subtleties around animated
movement; namely: moving actors out of their containers; anchor
points and movement; moving in the depth axis; interactions
between animated movement and constraints.

e92b186719 cookbook: Add recipe about sync'ing actor sizes
The recipe covers how to use ClutterBindConstraint
to bind actor sizes together.

It gives some examples of where this approach is appropriate,
as well as explaining an alternative using allocation-changed
or notify::* signals.

Three examples are given:

1. Resizing a texture to the stage.
2. Resizing a rectangle to act as a transparent overlay on
top of a texture (using constraints).
3. Resizing a rectangle to act as a transparent overlay on
top of a texture, but with a size proportional to the texture
(using a handler connected to allocation-changed signals
emitted by the texture).

e8e360eaa7 cookbook: Added a recipe for reusing a complex animation
This recipe explains how to "reuse" the same animation
definition for different actors, by creating a new
instance of a "rig" (empty container) and animation
for the rig each time the animation is required.

An actor is then re-parented to the rig and animated
using it, rather than being animated directly.

JSON is used to define the rig + animator, to make
creating new instances of them simpler. The recipe
also discusses various caveats around using this
approach, rather than directly animating an actor.

655c60aaa9 cookbook: Added recipe for complex animation
Uses ClutterAnimator to implement a reasonably complex
animation of a single actor (movement along a path with
simultaneous scaling).

Provides a metaphor for thinking about ClutterAnimator
animations (stage directions) and explains keys and key
frames in some depth. Also compares ClutterAnimator
with other possible approaches to this type of animation
(implicit animations, ClutterState).

ce3a3d4404 cookbook: Use text for callouts in documentation

are rendered as text rather than graphics (removes the need
to add callout graphics to the build).

81481cd803 cookbook: Added recipe for handling pointer events on an actor
Added a recipe about handling enter, leave, and motion events
on an actor.

Gives some pointers to data available from motion events,
explains a bit about stage-relative and actor-relative coords,
and covers how overlapping actors and reactivity of actors
can affect events occurring.

Examples include a simple scribble app showing how to integrate
pointer events into a more useful context.

b4f4942e07 cookbook: Add the source XML files as dependencies in the Makefile rules
The generated cookbook files (either HTML or PDF) do not only depend on
clutter-cookbok.xml but also on all the chapters that compose the
cookbook. Add this dependency to the Makefile rules to have make rebuild
the book when a chapter changes.

Since XML_FILES is now the list of source files, move recipe-template.xml
to EXTRA_DIST.

7ed3517504 cookbook: Added recipe for animated rotation of an actor
New recipe covering how to animate rotation of
an actor (in all axes).

Covers various factors affecting rotation animation
(like orientation of axes, parent rotation/orientation),
as well as trying to make rotations easier to visualise
(e.g. describing how rotation direction is affected by
those factors, how a rotation can be expected to look
when animated). Uses implicit animations for code examples.

Also refers to a full code example which uses ClutterState.

are visible through it.

1d9c64ff16 cookbook: Added support for inline video
Amended Makefile to copy content of videos directory into
installation directories. Also copies videos and images
into the html/ directory during the build, so that the
built cookbook can be viewed locally (for testing without
having to install).

Added an XSLT template to transform Docbook <inlinemediaobject>
elements into HTML 5 <video> elements, with a fallback to
link to the video displayed for browsers without HTML 5 support.

Added note to "Contributing" appendix explaining how to put
video into a recipe.

requires knowledge of the Clutter API and framework.
