6 - make dash length available

50 - should split also allow the user to pass arclens (instead of params)
51 - there are many occurences of 1e-5 left. Should they be replaced by the global _epsilon,
52 which would change the constructors to epsilon=None... if epsilon is None: epsilon=_epsilon
54 - what should we do for palette when only one entry
56 - is the early conversion with unit.topt unit-modification-save?
58 - better names for the helper functions ?
