Added 3 examples for the box layout recipe:
1) Simple box layout demonstrating how to set actor properties
2) Trivial menu implementation using box layout
3) Demonstration app which enables tweaking and testing
of layout property interactions
Also inlined example 1 in the solution section and added
more explanatory text in the discussion.
Other frameworks expose the same functionality as "auto-reverse",
probably to match the cassette tape player. It actually makes sense
for Clutter to follow suit.
clutter_timeline_set_reverse() can be used to
automatically reverse a timeline's direction each time
it completes, so use that in looping animation recipe and
examples.
Added an example showing scaling of an actor on
each of the scaling gravity settings (NORTH_WEST, NORTH etc.),
with a mark indicating the center being used.
Displays the transformed size and position, updated
on each paint of the actor.

Added an example showing how to move two actors between
two states (one minimised, one maximised) using ClutterState
to do the movement. Also shows how movement can be mixed
with other animation (in this case, scaling).
An alternative method (not using constraints) to bind
one actor's size and position to another. Used as
an example in the recipe about resizing one actor in
sync with a source actor.
A simple example showing how to scale an actor to the stage.
Demonstrates ClutterBindConstraint and ClutterAlignConstraint
in a fashion suitable for a short recipe.
Example code which loads an image into a texture, and resizes
the image in response to +/- key presses. The overlay is
a transparent rectangle which is bound to the height and
width of the texture; on clicking the texture, the overlay
is made visible by increasing its opacity.
This demonstrates how to use constraints to simplify code
for resizing an actor which is "dependent" on another actor.
Modified the "animation reuse" sample code to provide
a simpler example to explain in the recipe.
Also modified variable names to mirror the names used
for the previous "complex animation" example and added
some more comments, to further simplify and support the
recipe.
With some help from pippin, moved variable declarations
into more sensible positions within their functions,
changed a function name, and found a better way
to unref a script once its associated actor has
been destroyed.
Extracted the animation into its own JSON definition,
then create a new script and get the animation each
time a rectangle is clicked.
Removes the need to reparent onto the background and
copy property values to the rectangle after the animation,
and generally much cleaner.
Added an example showing how to reuse a ClutterAnimator
instance to animate multiple actors at different times
using an animatable rig, combined with reparenting.
Added another JSON example to show how transitions can
be easily overlapped when using ClutterAnimator (two
sequences of 5 transitions, simultaneous with two
sequences of 1 transition).
Modified the C JSON loader program so it can be used with
this example as well.
GEnum nicknames can be used to set properties in JSON
definitions, so added a callout to the JSON example explaining
this, and showing how to derive the nickname for an enumeration
value.
Modified the example code to use nicknames as well.
Commented the ClutterScript example so it can be used
inline as part of the recipe, rather than as an
example in the appendix (it's too simple to warrant
a separate appendix).
There was too much in the example code to cover in a single
recipe, so I trimmed it down to demonstrate simple
UI building (no constraints, effects, animations, or signals).
Added a simple script and program to load it, to support
recipe on ClutterScript for UI definitions.
Also amended the Makefile (following the pattern of
the tests/interactive Makefile) to enable signal
connection from ClutterScript by passing -export-dynamic
to linker.

Post-release version bump to 1.3.13
Release Clutter 1.3.12 (developers snapshot)
Conflicts:

Added another example (used for a screenshot) to demonstrate
how pointer events pass through non-reactive actors and how
depth ordering affects whether an actor will emit a pointer
motion signal.
Use clutter_event_get_coords() to get x and y position,
rather than casting to the right event type then directly
accessing members of the event struct.
Decided might be better to cover crossing and motion under
a broader "pointer motion" recipe, so renamed the example
(which only shows pointer crossing event handling).
Added a video showing the two texture cross-fade.
Modified the example code to animate on key press, so
this video could be captured.
Also altered the stage size to minimise the video size.
