Moving the ends of hairpins
The ends of hairpins may be offset by setting the shorten-pair property of the Hairpin object. Positive values move endpoints to the right, negative to the left. Unlike the minimum-length property, this property only affects the appearance of the hairpin; it does not adjust horizontal spacing (including the position of bounding dynamics). This method is thus suitable for fine-tuning a hairpin within its allotted space.
