Add a track to the timeline.
If the timeline already contains clips, then this may trigger the creation of their core track element children for the track, and the placement of the clip's children in the track of the timeline using select_tracks_for_object. Some errors may occur if this would break one of the configuration rules for the timeline in the track. In such cases, some track elements would fail to be added to the track, but this method would still return true . As such, it is advised that you avoid adding tracks to timelines that already contain clips.
