public void add_track_widget (Widget widget)
Adds a "track widget" to the ruler.
The ruler will connect to GtkWidget:motion-notify-event: on the track widget and update its position marker accordingly. The marker is correctly updated also for the track widget's children, regardless of whether they are ordinary children of off-screen children.
