I went ahead and worked some more on this.  (It took me long enough to figure 
out how to do this stuff, so I might as well put it to use so others can 
benefit too.)

See the attached file for another revision that implements these things:
- dots indicating octaves
- lines indicating note and rest durations
- correctly determines Jianpu note number (c major key: c = 0, c minor key: c = 
6, etc.)

It works by incorporating these symbols into the note head stencil.

This is just a quick sketch that can be improved and refined in terms of 
spacing and other details.  Some things still to do are handling dotted notes 
(I haven’t been able to access the dots grob from note head grob, so this seems 
tricky) and Jianpu accidental signs (which will require their own engraver).

HTH,
