Actually, no. To work, \offset needs access to a default value--a number,
number-pair, or list of number-pairs--or a default procedure to calculate
these values with. If you don't find an entry in define-grobs.scm, it will
have nothing to work with.
DynamicLineSpanner.padding works because it's set by default to 0.6.
