47 - support single-character mode
49 - should split also allow the user to pass arclens (instead of params)
50 - there are many occurences of 1e-5 left. Should they be replaced by the global _epsilon,
51 which would change the constructors to epsilon=None... if epsilon is None: epsilon=_epsilon
53 - what should we do for palette when only one entry
55 - is the early conversion with unit.topt unit-modification-save?
57 - better names for the helper functions ?
58 - why does smoothed through away short normpathitems instead of simply ignoring them?
