* SECTION:clutter-animation
* @short_description: Simple implicit animations
* @See_Also: #ClutterAnimatable, #ClutterInterval, #ClutterAlpha,
* #ClutterTimeline
*
* #ClutterAnimation is an object providing simple, implicit animations
* for #GObject<!-- -->s.
*
* #ClutterAnimation instances will bind a #GObject property belonging
* to a #GObject to a #ClutterInterval, and will then use a #ClutterTimeline
* to interpolate the property between the initial and final values of the
* interval.
* #ClutterAnimation instances will bind one or more #GObject properties
* belonging to a #GObject to a #ClutterInterval, and will then use a
* #ClutterAlpha to interpolate the property between the initial and final
* values of the interval.
*
* The duration of the animation is set using clutter_animation_set_duration().
* The easing mode of the animation is set using clutter_animation_set_mode().
*
* If you want to control the animation you should retrieve the
* #ClutterTimeline using clutter_animation_get_timeline() and then
* use #ClutterTimeline functions like clutter_timeline_start(),
* clutter_timeline_pause() or clutter_timeline_stop().
*
* A #ClutterAnimation will emit the #ClutterAnimation::completed signal
* when the #ClutterTimeline used by the animation is completed; unlike
* #ClutterTimeline, though, the #ClutterAnimation::completed will not be
* emitted if #ClutterAnimation:loop is set to %TRUE - that is, a looping
* animation never completes.
*
* If your animation depends on user control you can force its completion
* using clutter_animation_completed().
*
* If the #GObject instance bound to a #ClutterAnimation implements the
* #ClutterAnimatable interface it is possible for that instance to
* control the way the initial and final states are interpolated.
*
* #ClutterAnimation<!-- -->s are distinguished from #ClutterBehaviour<!-- -->s
* because the former can only control #GObject properties of a single
* #GObject instance, while the latter can control multiple properties
* using accessor functions inside the #ClutterBehaviour::alpha_notify
* virtual function, and can control multiple #ClutterActor<!-- -->s as well.
*
* For convenience, it is possible to use the clutter_actor_animate()
* function call which will take care of setting up and tearing down

* @short_description: A logical distance unit
*
* Clutter units are logical units with granularity greater than that of the
* device units; they are used by #ClutterActorBox and the units-based family
* of #ClutterActor functions. To convert between Clutter units and device
* units, use %CLUTTER_UNITS_FROM_DEVICE and %CLUTTER_UNITS_TO_DEVICE macros.
* #ClutterUnits is a structure holding a logical distance value along with
* its type, expressed as a value of the #ClutterUnitType enumeration. It is
* possible to use #ClutterUnits to store a position or a size in units
* different than pixels, and convert them whenever needed (for instance
* inside the #ClutterActor::allocate() virtual function, or inside the
* #ClutterActor::get_preferred_width() and #ClutterActor::get_preferred_height()
* virtual functions.
*
* #ClutterUnit<!-- -->s can be converted from other units like millimeters,
* typographic points (at the current resolution) and percentages. It is
* also possible to convert fixed point values to and from #ClutterUnit
* values.
*

* G_PARAM_READWRITE);

*
* A #GValue holding units can be manipulated using clutter_value_set_unit()

* values - with a loss of precision:

* Blending occurs after the alpha test function, and combines fragments with

* <para>
* A fixed function is used to determine the blended color, which is based on
* the incoming source color of your fragment (Rs, Gs, Bs, As), a source
* factor (Sr, Sg, Sb, Sa), a destination color (Rd, Rg, Rb, Ra) and
* a destination factor (Dr, Dg, Db, Da), and is given by these equations:
* </para>
* Currently the only blend function Cogl exposes is ADD(). So any valid
* blend statements will be of the form:
*
* <programlisting>
* R = Rs*Sr + Rd*Dr
* G = Gs*Sg + Gd*Dg
* B = Bs*Sb + Bd*Db
* A = As*Sa + Ad*Da
* &lt;channel-mask&gt;=ADD(SRC_COLOR*(&lt;factor&gt;), DST_COLOR*(&lt;factor&gt;))
* </programlisting>
*
* All factors have a range [0, 1]
* <b>NOTE: The brackets around blend factors are currently not optional!</b>
*
* The factors are selected with the following constants:
* This is the list of source-names usable as blend factors:
* <itemizedlist>
* <listitem>SRC_COLOR: The color of the in comming fragment</listitem>
* <listitem>DST_COLOR: The color of the framebuffer</listitem>
* <listitem>
* CONSTANT: The constant set via cogl_material_set_blend_constant()</listitem>
* </itemizedlist>
* The source names can be used according to the
* <link linkend="cogl-Blend-String-syntax">color-source and factor syntax</link>,
* so for example "(1-SRC_COLOR[A])" would be a valid factor, as would
* "(CONSTANT[RGB])"
*
* These can also be used as factors:
* <itemizedlist>
* <listitem>0: (0, 0, 0, 0)</listitem>
* <listitem>1: (1, 1, 1, 1)</listitem>

I think it would be be really neat to support a simple string description
of the fixed function texture combine modes exposed above. I think we can
consider this stuff to be set in stone from the POV that more advanced
texture combine functions are catered for with GLSL, so it seems reasonable
to find a concise string representation that can represent all the above
modes in a *much* more readable/useable fashion. I think somthing like
this would be quite nice:
"MODULATE(TEXTURE[RGB], PREVIOUS[A])"
"ADD(TEXTURE[A],PREVIOUS[RGB])"
"INTERPOLATE(TEXTURE[1-A], PREVIOUS[RGB])"
