36 - perform calc by means of Python itself (see eval code in graph.data, but
37 we should use compiled code instead of eval)
39 - think hard about different paths in decoratedpath class
40 - adjust parameters of cycloid and smoothed
41 AW suggests to use cycloid with default curvesperloop=5.
43 - support single-character mode

155 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
157 - added inplace add (__iadd__), enlarge and transform methods
