Detailed Description

An in-session identifier of track objects across undo states. It does not persist between sessions.

Default constructed value is not equal to the id of any track that has ever been added to a TrackList, or (directly or transitively) copied from such. (A track added by TrackList::RegisterPendingNewTrack() that is not yet applied is not considered added.)

TrackIds are assigned uniquely across projects.
