From 19b537a142c127dd2c1d9a40a7999714f9d2175d Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 2 Mar 2007 00:05:18 +0000
Subject: Work towards Action serialization. Made edge length in dot graphs
 (from machina2dot) correspond to node duration to make automaton diagram map
 closer to music notation.
