21 (When plotted, the graph does not complain, but the postscript will be broken)
23 - multi page PostScript output
24 - contructor should only take a texrunner keyword argument
28 - style and color module:
29 - support modification of existing styles via __call__
31 - height -> getheight, ...
33 - TODO: general documentation about attributes, clearing, merging?
34 - TODO: general documentation about changeable attributes?
36 - what about unit.cm() -> unit.cm, ...
37 - maybe we should never convert implicitly into visual/width, etc. lengths
38 - check that we always return the appropriate length, i.e., not
41 - might be moved into the graph
42 - perform calc by means of Python itself (see eval code in graph.data, but
43 we should use compiled code instead of eval)

47 AW suggests to use cycloid with default curvesperloop=5.
49 - support single-character mode
51 - arclentoparam should raise an exception when the arclen is out of range
52 - use _pt for variable names
53 - it seems to be, that epsilon is a feature of normsubpath;
54 Why is there (also) a self.epsilon?
55 - Why is there no normpathel.trafo()? And how about
56 normpathel.begintrafo() and normpathel.endtrafo()?
61 - more details in path constructor: allowed pathels, first pathel...
66 Attributes and changeable attributes should be explained in a

142 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
144 - added inplace add (__iadd__), enlarge and transform methods
145 - callers use inplace add where possible now (yielding a considerable
147 - "undefined" corners of bounding boxes are no longer supported which makes
