+/**
+ * SECTION:clutter-alpha
+ * @short_description: A class for calculating a value as a function of time
+ *
+ * #ClutterAlpha is a class for calculating an floating point value
+ * dependent only on the position of a #ClutterTimeline.
+ *
+ * For newly written code, it is recommended to use the
+ * #ClutterTimeline:progress-mode property of #ClutterTimeline, or the
+ * clutter_timeline_set_progress_func() function instead of #ClutterAlpha.
+ * The #ClutterAlpha class will be deprecated in the future, and will not
+ * be available any more in the next major version of Clutter.
+ *
+ * A #ClutterAlpha binds a #ClutterTimeline to a progress function which
+ * translates the time T into an adimensional factor alpha.
+ *
+ * You should provide a #ClutterTimeline and bind it to the #ClutterAlpha
+ * instance using clutter_alpha_set_timeline(). You should also set an
+ * "animation mode", by using the #ClutterAnimationMode values that
+ * Clutter provides.
+ *
+ * Instead of a #ClutterAnimationMode you may provide a function returning
+ * the alpha value depending on the progress of the timeline, using
+ * clutter_alpha_set_func() or clutter_alpha_set_closure(). The alpha
+ * function will be executed each time a new frame in the #ClutterTimeline
+ * is reached.
+ *
+ * Since the alpha function is controlled by the timeline instance, you can
+ * pause, stop or resume the #ClutterAlpha from calling the alpha function by
+ * using the appropriate functions of the #ClutterTimeline object.
+ *
+ * #ClutterAlpha is available since Clutter 0.2.
+ *
+ * #ClutterAlpha is deprecated since Clutter 1.12. #ClutterTimeline and
+ * the #ClutterTimeline:progress-mode property replace this whole class.
+ *
+ * ## ClutterAlpha custom properties for #ClutterScript
+ *
+ * #ClutterAlpha defines a custom `function` property for
+ * #ClutterScript which allows to reference a custom alpha function
+ * available in the source code. Setting the `function` property
+ * is equivalent to calling clutter_alpha_set_func() with the
+ * specified function name. No user data or #GDestroyNotify is
+ * available to be passed.
+ *
+ * The following JSON fragment defines a #ClutterAlpha
+ * using a #ClutterTimeline with id "sine-timeline" and an alpha
+ * function called `my_sine_alpha`.
+ *
+ * |[
+ * {
+ *   "id" : "sine-alpha",
+ *   "timeline" : {
+ *     "id" : "sine-timeline",
+ *     "duration" : 500,
+ *     "loop" : true
+ *   },
+ *   "function" : "my_sine_alpha"
+ * }
+ * ]|
