In case anyone cares, I finally was able to determine the
reference points for the individual non-staff lines. Here
they are:
CONTEXT REFERENCE POINT
----------- ---------------
ChordNames baseline
NoteNames baseline
Lyrics baseline
Dynamics vertical center
FiguredBass highest point
FretBoards guitar nut
I'll add this to the doc patch and push it:

The test file I used follows below; I attached a png too.
