Thanks -- makes a lot more sense to me now.

Not currently.  I suppose the best way would be to allow for
dash-definition in lily/line-interface.cc, so it could be read from
the grob.  But you could go the replacement stencil route.  I'm
guessing that you could make good use of Harm's code above as a
framework.

No time right now, but I should post my Scheme version of
ly:hairpin::print, so you can meddle directly with hairpins without
building a stencil solely for dimension info, then throwing it away.
