b3784bd2b4 event: Add a setter for the device field
When synthesizing events coming from input devices it should be
possible to just call a setter function, to avoid a huge switch
on the type of the event.

Clutter should also store the device pointer inside the private
data, for faster access of the pointer in allocated events.

Finally, the get_device_id() and get_device_type() accessors should
just be wrappers around clutter_event_get_device(), to reduce the
amount of code duplication.

326c516304 cogl: rename CoglVertexAttribute CoglAttribute
This is part of a broader cleanup of some of the experimental Cogl API.
One of the reasons for this particular rename is to reduce the verbosity
of using the API. Another reason is that CoglVertexArray is going to be
renamed CoglAttributeBuffer and we want to help emphasize the
relationship between CoglAttributes and CoglAttributeBuffers.

b9f7ef1110 build: Remove Cogl2 reference from the build scripts
Keeping the Cogl 2.0 API reference in the build is getting far more
troublesome than it's worth.

It's breaking distcheck far too often, and it makes it impossible to
rebuild the build environment from tarballs - which is something that
some distributions (namely: the Debian-based ones, but not limited to
them) do in order to change build scripts using their own rules.

88f7579a9d cookbook: Remove bold on emphasis inside programlisting
If an <emphasis> element is placed inside a <programlisting> in a cookbook
recipe, the result is bold italic text in the HTML output. This isn't
particularly readable.

Fix is to style emphasis elements inside programlistings
so the font weight is not bold but is still italicised.

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.

2dba3e8cbf matrix: Adds experimental cogl_matrix_{transform,project}_points
This add two new function that allows us to transform or project an
array of points instead of only transforming one point at a time. Recent
benchmarking has shown cogl_matrix_transform_point to be a bottleneck
sometimes, so this should allow us to reduce the overhead when
transforming lots of vertices at the same time, and also reduce the cost
of 3 component, non-projective transforms.

For now they are marked as experimental (you have to define
COGL_ENABLE_EXPERIMENTAL_API) because there is some concern that it
introduces some inconsistent naming. cogl_matrix_transform_point would
have to be renamed cogl_matrix_project_point to be consistent, but that
would be an API break.

b55346151c build: Cogl-2.0 API reference should be conditionally built
Building the API reference for Cogl 2.0 is fairly confusing: the API
itself is experimental and for internal use only -- though we want
feedback for it.

Let's build the API reference only when Clutter is configured with a
specific configure switch, so that people that wish to give feedback on
the API and its documentation can do it.

Since EGA colors are apparently all the rage in other toolkits, Clutter

pleasant to the eye.

Static colors are accessed through an enumeration by using
clutter_color_get_static(), or using the short-hand pre-processor
macros.

e66c679e84 win32: Add a public clutter_win32_handle_event function
This function handles a single windows message. The idea is that it
could be used by clutter-gtk to forward on events from a
GdkEventFilter. The function replaces the old message_translate()
function. That function didn't translate the event anymore anyway and
instead it could generate multiple events so
clutter_win32_handle_event seems like a more appropriate name. The
function returns TRUE or FALSE depending on whether the event was
completely handled instead of setting call_window_proc.

66b0c1969c Remove the internal copy of JSON-GLib
The internal copy of JSON-GLib was meant to go away right after the 1.0
release, given that JSON-GLib was still young and relatively unknown.

Nowadays, many projects started depending on this little library, and
distributions ship it and keep it up to date.

Keeping a copy of JSON-GLib means keeping it up to date; unfortunately,
this would also imply updating the code not just for the API but for the
internal implementations.

Starting with the 1.2 release, Clutter preferably dependend on the
system copy; with the 1.4 release we stopped falling back automatically.
The 1.6 cycle finally removes the internal copy and requires a copy of
JSON-GLib installed on the target system in order to compile Clutter.

37d0dbe6b2 docs: Put deprecated Cogl symbols into new section
This adds a "Cogl deprecated API" chapter to the Cogl reference manual
so we can group all the documentation for deprecated symbols together
instead of having them clutter up the documentation of symbols we would
rather developers used.

2bc739ab44 docs: cogl-texture-3d wasn't listed as experimental
The CoglTexture3D API is only available when defining
COGL_ENABLE_EXPERIMENTAL_API so it should be listed in the experimental
section of the API reference.

a89b8f4304 docs: Use "Cogl" not "COGL" in Cogl API reference
Cogl isn't an acronym so we should use "Cogl" instead of "COGL" in
our documentation.

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).

c3cbf1533f cookbook: Example using allocation-changed to sync actor size
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.

8a149521ce cookbook: Simple example to demonstrate bind constraint
A simple example showing how to scale an actor to the stage.

Demonstrates ClutterBindConstraint and ClutterAlignConstraint
in a fashion suitable for a short recipe.
