6 - make dash length available

16 - 3d graphs, circular graphs
17 - graph.style and graph.data modules
18 - exceptions in drawsymbol & friends...
19 - caution: another reorganization round is in progress
20 (its goal is to make graph styles combinable which will also
21 split up the style code in smaller parts -- those will then be
22 easier to substitute by inheritance)
24 - use csv module (new in 2.3)
25 - Check for "inf" and "nan" in datafiles.

43 we should use compiled code instead of eval)
45 - think hard about different paths in decoratedpath class
46 - adjust parameters of cycloid and smoothed
47 AW: I suggest 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 - there are two epsilons related to normpath, one in the normpath and
53 one in the subnormpath; while the later seems a clear feature, the first
54 might be a misdesign; a solution is still pending ...
56 - what should we do for palette when only one entry
58 - is the early conversion with unit.topt unit-modification-save?
63 - more details in path constructor: allowed pathels, first pathel...
68 Attributes (clearing merging ) and changeable attributes should be
69 explained at a central place.
70 - section titles: "Axes" -> "Axes - module axis" or similar
72 - linealign and circlealign

123 - graph.axis.painter.plain -> graph.axis.painter.regular
124 (as it was in parts of the documentation already)
125 - changeable-gridattrs-become-None-bug fixed
126 - graph style cutting outside lines (double-)fixed
129 - fixes missing install of the graph and axis directories introduced in 0.6

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