4533edeef0 cookbook: Further clarification of the anchor point
Make sure to add a note on the behaviour of the anchor point. Ideally,
it would be nice to have a recipe about it in the Actor section.

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).

a0f63a3153 cookbook: Example of using a bind constraint for an overlay
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.

f5f066df9c Try to clean up how we handle actor transformations
When building actor relative transforms, instead of using the matrix
stack to combine transformations and making assumptions about what is
currently on the stack we now just explicitly initialize an identity
matrix and apply transforms to that.

This removes the full_vertex_t typedef for internal transformation code
and we just use ClutterVertex.

ClutterStage now implements apply_transform like any other actor now
and the code we had in _cogl_setup_viewport has been moved to the
stage's apply_transform instead.

ClutterStage now tracks an explicit projection matrix and viewport
geometry. The projection matrix is derived from the perspective whenever
that changes, and the viewport is updated when the stage gets a new
allocation. The SYNC_MATRICES mechanism has been removed in favour of
_clutter_stage_dirty_viewport/projection() APIs that get used when
switching between multiple stages to ensure cogl has the latest
information about the onscreen framebuffer.

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.

4ee05f8e21 keysyms: Update the macros to CLUTTER_KEY_*
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.

This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:

  - clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
  - clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*

The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.

This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.

71a4db6135 animation: Allow detaching an animation from an actor
When animating an actor through clutter_actor_animate() and friends we
might want forcibly detach the animation instance from the actor in
order to start a new one - for instance, in response to user
interaction.

Currently, there is no way to do that except in a very convoluted way,
by emitting the ::completed signal and adding a special case in the
signal handlers; this is due to the fact that clutter_actor_animate()
adds more logic than the one added by clutter_animation_set_object(),
so calling set_object(NULL) or unreferencing the animation instance
itself won't be enough.

The right way to approach this is to add a new method to Clutter.Actor
that detaches any eventual Animation currently referencing it.

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).

12a5bf2e06 offscreen-effect: Rename create_target to create_buffer
*** This is an API change ***

The create_target() virtual function should return a CoglHandle to a
texture; clutter_offscreen_effect_get_target(), instead, returns a
CoglMaterial to be painted in the implementation of the paint_target()
virtual function.

Instead of equating textures with materials, and confusing the user of
the API, we should mark the difference more prominently.

First of all, we should return a CoglMaterial* (now that we have that
as a public type) in get_target(); having handles all over the place
does not make it easier to distinguish the semantics of the virtual
functions.

Then we should rename create_target() to create_texture(), to make it
clear that what should be returned is a texture that is used as the
backing for the offscreen framebuffer.
