24 - tuplet bracket should probably be subject to the same rules as
25 beam sloping/quanting.
27 - There is no support for kneed brackets, or nested brackets.
29 - number placement for parallel beams should be much more advanced:
30 for sloped beams some extra horizontal offset must be introduced.
32 - number placement is usually done over the center note, not the
37 TODO: quantise, we don't want to collide with staff lines.
38 (or should we be above staff?)
40 todo: handle breaking elegantly.
