aece642adb doc: fix clutter_init() usage in examples
Make sure users get the idea that clutter_init()
has a return value that needs to be checked.

These were fixed via sed magic:

sed -i -s -e "s/clutter_init (.*)/\
if (& != CLUTTER_INIT_SUCCESS)\n    return 1/"\
 doc/*/*/*.{c,xml} doc/*/*.xml

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.

885664f725 docs: Explain why destroy() is implemented
As destroy() is Clutter-specific and not generic
GObject code, explain why we implement it
(rather than dispose()).

Elliot Smith
e69d60e8b6 docs: Implement destroy() rather than dispose()
Remove the dispose() implementation and replace
with destroy().

This should be promoted as the standard approach
for implementing a composite actor, as it emits a
signal when instances of the actor subclass are destroyed.

c444447cd3 timeline: Rename the reverse property to auto-reverse
Other frameworks expose the same functionality as "auto-reverse",
probably to match the cassette tape player. It actually makes sense

c9d0f8b26e cookbook: Add recipe for animated scaling of an actor
Recipe explains how to animate scaling a single actor.

Also covers scaling vs. resizing, scale center, and
scaling within layouts and containers.

The first example shows how animations around each scale
gravity look, as well as tracking the transformed position
and size of the actor and displaying those.

The second example is a simple image viewer with zoom in/out
using scaling.

(the criteria for how clicks get counted, including
distance and time settings); how button numbers are reported;

for press + release in certain scenarios.
