6 - make dash length available
8 - SlantFont & Co support

17 - axis painter labelattrs=None + automatic axis partitioning leads to no valid partitioning
18 - graph.style and graph.data modules
19 - exceptions in drawsymbol & friends...
20 - caution: another reorganization round is in progress
21 (its goal is to make graph styles combinable which will also
22 split up the style code in smaller parts -- those will then be
23 easier to substitute by inheritance)
25 - use csv module (new in 2.3)
26 - Check for "inf" and "nan" in datafiles.

48 - support single-character mode
50 - arclentoparam should raise an exception when the arclen is out of range
51 - there are two epsilons related to normpath, one in the normpath and
52 one in the subnormpath; while the later seems a clear feature, the first
53 might be a misdesign; a solution is still pending ...
55 - what should we do for palette when only one entry
57 - is the early conversion with unit.topt unit-modification-save?
59 - better names for the helper functions ?
64 - more details in path constructor: allowed pathels, first pathel...
69 Attributes (clearing merging ) and changeable attributes should be
70 explained at a central place.
71 - section titles: "Axes" -> "Axes - module axis" or similar
73 - linealign and circlealign
77 - describe creation and modification (inplace and ``modify by new'') of

83 having a _pt suffix when containing lengths in points
85 - names of local and member variables now follow the naming convention of

190 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
192 - added inplace add (__iadd__), enlarge and transform methods
193 - callers use inplace add where possible now (yielding a considerable
195 - "undefined" corners of bounding boxes are no longer supported which makes
196 the bounding box operations much more efficient.
