/**
* clutter_effect_template_new_for_duration:
* @msecs: the duration of the effects, in milliseconds
* @alpha_func: an alpha function to use for the template
*
* Creates a new #ClutterEffectTemplate, to be used with the effects API.
*
* A #ClutterEffectTemplate binds a timeline and an alpha function and can
* be used as a template for multiple calls of clutter_effect_fade(),
* clutter_effect_move() and clutter_effect_scale().
*
* This API is intended for simple animations involving a single actor;
* for more complex animations, you should see #ClutterBehaviour and the
* derived classes.
*
* This function creates a #ClutterTimeline with a duration of @msecs
* milliseconds and transfers ownership of the timeline object to the
* returned #ClutterEffectTemplate.
*
* Return value: the newly created #ClutterEffectTemplate object
*
* Since: 0.6
