public bool set_active_for_tracks (bool active, List<Track>? tracks)
Activate or deactivate track elements in tracks (or in all tracks if tracks is null
).
When a layer is deactivated for a track, all the TrackElement-s in the track that belong to a Clip in the layer will no longer be active in the track, regardless of their individual active value.
Note that by default a layer will be active for all of its timeline's tracks.
