Robert Bragg d1434d1c33 math: Adds an experimental quaternion API
This adds an experimental quaternion utility API. It's not yet fully
documented but it's complete enough that people can start to experiment
with using it. It adds the following functions:

    cogl_quaternion_init_identity
    cogl_quaternion_init
    cogl_quaternion_init_from_angle_vector
    cogl_quaternion_init_from_array
    cogl_quaternion_init_from_x_rotation
    cogl_quaternion_init_from_y_rotation
    cogl_quaternion_init_from_z_rotation
    cogl_quaternion_equal
    cogl_quaternion_copy
    cogl_quaternion_free
    cogl_quaternion_get_rotation_angle
    cogl_quaternion_get_rotation_axis
    cogl_quaternion_normalize
    cogl_quaternion_dot_product
    cogl_quaternion_invert
    cogl_quaternion_multiply
    cogl_quaternion_pow
    cogl_quaternion_slerp
    cogl_quaternion_nlerp
    cogl_quaternion_squad
    cogl_get_static_identity_quaternion
    cogl_get_static_zero_quaternion

Since it's experimental API you'll need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.

<title>Cogl - a modern 3D graphics API</title>
<section id="cogl-intro">
<title>About Cogl</title>
<para>Cogl is a modern 3D graphics API with associated utility
APIs designed to expose the features of 3D graphics hardware
using a more object oriented design than OpenGL. The library has
primarily been driven by the practical needs of Clutter but it
is not tied to any one toolkit or even constrained to developing
UI toolkits.</para>

<title>Cogl experimental API</title>
<section id="cogl-experimental">
<title>About the experimental API</title>
<para>Cogl has some experimental API developers are welcomed to play
with. The main drawback when using those is that there is no API
stability guarantee, functions flagged as experimental could be changed
or removed in future versions of the library. To use this experimental
API you will need to define
<literal>COGL_ENABLE_EXPERIMENTAL_API</literal> before including
<filename class="headerfile">&lt;clutter/clutter.h&gt;</filename> or
<filename class="headerfile">&lt;cogl/cogl.h&gt;</filename>.</para>

<title>Cogl deprecated API</title>
<section id="cogl-deprecated">
<title>About the deprecated API</title>
<para>Cogl has evolved from once being a thin abstraction over
OpenGL and GLES where a lot of OpenGL's state machine style APIs
were simply rebranded as Cogl API into the more distinguished API
style we have today. The result of this evolution though is that
some of the APIs are considered deprecated and because we plan to
remove them at the next opportunity we have to break the API
developers should aim to avoid these functions to keep their code
working with future major versions of Cogl.</para>
