/**
* HippoAnimation::
*
* The HippoAnimation class represents a single animation that can be managed by
* a HippoAnimationManager. An animation consists of a series of "events".
* events can either be instantantaneous, or they can have a duration. Each
* event is identified by an integer ID. (It was done this way rather than
* using objects to avoid forcing someone implementation an animation to
* define a new GObject type.)
*
* The base HippoAnimation class does nothing by itself. You can either
* subclass it, or you can create an instance of the base class and connect
* to the ::event and ::cancel signals.
