TODO:
- * Use Number_pair i.s.o Interval to represent (yl, yr).
-
- Determine auto knees based on positions if it's set by the user.
+ - the code is littered with * and / staff_space calls for
+ #'positions. Consider moving to real-world coordinates?
+ Problematic issue is user tweaks (user tweaks are in staff-coordinates.)
+
Notes:
-
- Stems run to the Y-center of the beam.
- beam_translation is the offset between Y centers of the beam.
