+% * breapth: Ignored (as far as I know). Should be set to 0.
+%
+% * width: Should cover the horizontal range of the custos that is to
+% be printed in the staff. If the custos has an appendage that is
+% supposed to reach beyond the right end of the staff, the width
+% should be set such that the appendage is outside of the char box.
+%
+% * depth: Should match the bottom edge of the custos. Affects
+% vertical collision handling.
+%
