Fixes to NoteLayer, particularly to calculation of vertical scale when model unit is not Hz. To avoid inconsistency we now behave as if the unit is always Hz from the point of view of the external API and display, converting at the point where we obtain values from the events themselves. Also various fixes to editing.
