Good stuff! Do we have something like this in the manual somewhere?
Otherwise I suggest that you add it as an example.
Not in the official manual, but there is some amount of
information in my “Extending LilyPond” document, specifically
in these sections:
https://extending-lilypond.readthedocs.io/en/latest/backend.html#properties-and-callbacks
https://extending-lilypond.readthedocs.io/en/latest/backend.html#coordinates-extents-and-reference-points
https://extending-lilypond.readthedocs.io/en/latest/backend.html#dummy-properties
(I would have to add ly:grob-translate-axis!).
Best,
Jean
