- * USE ME ONLY FOR CROSS STAFF SLURS!

- * the VerticalAxisGroups will be spaced very far apart to accommodate the
- * slur, which we don't want, as it is cross staff.

- * TODO: Currently, the code below keeps the topmost and bottommost axis
- * groups and gets rid of the rest. This should be more nuanced for
- * cases like ossias where the topmost staff changes over the course of
- * the slur. Ditto for the bottommost staff.
