    \brief AbstractClipAnimator is the base class for types providing animation playback
    capabilities.

    Subclasses of AbstractClipAnimator can be aggregated by an Entity to
    provide animation capabilities. The animator components provide an
    interface for controlling the animation (e.g. start, stop). Each animator
    type requires some form of animation data such as an AbstractAnimationClip
    as well as a ChannelMapper which describes how the channels in the
    animation clip should be mapped onto the properties of the objects you wish
    to animate.

    The following subclasses are available:

    \list
    \li Qt3D.Animation.ClipAnimator
    \li Qt3D.Animation.BlendedClipAnimator
