5 - common bboxes for different graphs
6 - exceptions in drawsymbol & friends...
7 - 3d graphs, circular graphs
10 - make dash length available
12 - SlantFont & Co support
13 - keep an eye on PEP 324 (popen 5): it could make the texrunner much easier
14 - messageparser for replaced fontsizes: Warning
15 - messageparser for size differences at the end: Warning not Exception
16 - messageparser for overfull/underfull vbox/hbox: Warning not Exception
17 - newline removal when not disturbing texmessages only
19 - consider rewrite using the python compiler module
21 - use csv module (new in 2.3)

23 (When plotted, the graph does not complain, but the postscript will be broken)
25 - multi page PostScript output
26 - contructor should only take a texrunner keyword argument
30 - style and color module:
31 - support modification of existing styles via __call__
33 - height -> getheight, ...
35 - TODO: general documentation about attributes, clearing, merging?
36 - TODO: general documentation about changeable attributes?
40 - what about unit.cm() -> unit.cm, ...
41 - maybe we should never convert implicitly into visual/width, etc. lengths
43 - might be moved into the graph
44 - perform calc by means of Python itself (see eval code in graph.data, but
45 we should use compiled code instead of eval)
49 - wriggle should be replaced by cycloid
50 - name for cycloid OK?
51 AW: Fine to me. I suggest to use curvesperloop=5. I think, it is not
52 crucial to 0.6 at all. Those decorators are working but are not yet
53 documented. We also need to think hard about decorators for 0.7 ...
55 - graph module: (in progress)
56 - axis zeropath feature removed
57 AW: Why bother with that in the documentation at all?
62 -> not always returns true
65 in the introduction mention the canvas
67 - AW remarks: Attributes and changeable attributes should be explained in a
68 central place. I guess that will not happen within 0.6 ...
72 - added inplace add (__iadd__), enlarge and transform methods
73 - callers use inplace add where possible now (yielding a considerable
75 - "undefined" corners of bounding boxes are no longer supported which makes
76 the bounding box operations much more efficient.

79 small pending issues, but the basic restructuring is done with this release):

87 - names and texts removed from baraxis
88 - iteration on graph style, when it is used several times in the same graph
89 - symbols + lines -> symbollines; symbols do not allow setting lineattrs,
90 and lines not symbolattrs
91 - manual line clipping (do not include unneeded line segments when the
92 axis range is set manually etc.)
93 - automatic file key titles
94 - graph.data now also includes the old data module

111 correspondingly for normpath)
112 - complete refactoring of the normpath class: normpaths now consist of
113 normsubpaths which themselves consist of normlines and normcurves This is
114 much more convenient for any routines working with normpaths.
115 - reversing of closed sub paths does not change the first point of the sub
117 - renamed: arclength -> arclen
118 - renamed: lentopar -> arclentoparam
119 - path and normpath method raise exception instead of returning None
120 when parameter is out of range
121 - the accuracy epsilon can now only be specified in normpath and normsubpath
122 constructor and no longer in arguments of path and normpath methods
123 - negative parameters are no longer supported in path and normpath methods
124 - path and normpath methods which accept parameter value param now
