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.
