6 - make dash length available
8 - SlantFont & Co support
9 - keep an eye on PEP 324 (popen 5): it could make the texrunner much easier

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.

84 having a _pt suffix when containing lengths in points
85 - enlarge was misspelled as enlarged
86 - renamed _bbox -> bbox_pt
87 - new bbox method center, which returns the coordinates of the center
89 - enlarge and enlarged do no longer interprete unqualified lengths as
92 - unit.cm, unit.t_cm, etc. are no longer sub classes but instances
94 - never convert implicitly into visual/width, etc. lengths (this is more
95 about usage of the unit module in various other modules) (TODO: update

98 easy to turn it on again (TODO: documentation)

116 - graph style cutting outside lines (double-)fixed
119 - fixes missing install of the graph and axis directories introduced in 0.6
120 - some minor updates to the faq

176 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
178 - added inplace add (__iadd__), enlarge and transform methods
179 - callers use inplace add where possible now (yielding a considerable
