I like the tunable idea. Perhaps a grob property named `avoids' that is a list of pairs, kinda like: '((bar-line . #t) (time-signature . #f) (note-head . #t)) etc... Then, we could use has_interface to weed out grobs for which we don't want to collision detect. As to your question: in scores by Ligeti, Bartok, and Schoenberg, and Xenakis, bar lines are not avoided. I cannot come up with an example off the top of my head where bar lines are avoided.
