The common part of the two clip kinds that produce a pose: AtomicClipData and ParametricClipData. It names the track the clip plays on, the mask that limits it to part of the body, and its sync group, and it holds the clip's events.
Map<Hash, BaseEventData> The events of the clip. The key is the hash of the event's name and only has to be
unique within the clip. Each value is one event, which
fires at its mStartFrame while the clip plays.
When the graph loads, the client writes the key into each event's mName.
Hash The mask of the clip, as a key of AnimationGraphData.mMaskDataMap. Empty, or a name
that is not in the map, means no mask: the clip has full weight on every joint.
Hash The sync group of the clip, as a key of AnimationGraphData.mSyncGroupDataMap.
Empty, or a name that is not in the map, means no group.
Hash The track the clip plays on, as a key of AnimationGraphData.mTrackDataMap. A clip
that starts replaces the clip that was on that track.
