clutter: Remove 'ClutterAlpha'
It was some kind of deprecated interpolation mechanism used in ClutterAnimation. We're not using it, and have non-deprecated replacement functionality, so lets drop it. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1192

/**
|
||||
* 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"
