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
10 - messageparser for replaced fontsizes: Warning
11 - messageparser for size differences at the end: Warning not Exception
12 - messageparser for overfull/underfull vbox/hbox: Warning not Exception
13 - newline removal when not disturbing texmessages only
15 - common bboxes for different graphs
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.
26 (When plotted, the graph does not complain, but the postscript will be broken)
28 - finish multi page PostScript output
29 - contructor should only take a texrunner keyword argument
33 - style and color module:
34 - support modification of existing styles via __call__
36 - height -> getheight, ...
38 - maybe we should never convert implicitly into visual/width, etc. lengths
40 - might be moved into the graph
41 - perform calc by means of Python itself (see eval code in graph.data, but
42 we should use compiled code instead of eval)
44 - think hard about different paths in decoratedpath class
45 - adjust parameters of cycloid and smoothed
46 AW: I suggest to use cycloid with default curvesperloop=5.
48 - support single-character mode
50 - arclentoparam should raise an exception when the arclen is out of range
51 - it seems to be, that epsilon is a feature of normsubpath;
52 AW: Why is there (also) a self.epsilon?
53 JL: What class does self refer to?
54 AW: I'm sorry for not being precise. Both, normpath and normsubpath do
55 have an epsilon. I'm not sure if we should do that (its slightly
56 confusing). In normpath._findsubpath we should refer to the
57 epsilons of the subpath. The only usage of epsilon left in normpath
58 is in the constructor and in append (BTW -- we do have some code
59 dublication here). A possibility would be to add a keyword-argument
60 epsilon to append. The point is, that I would like to get rid of
61 self.epsilon, where self is a normpath instance ...
63 - what should we do for palette when only one entry
68 - more details in path constructor: allowed pathels, first pathel...
73 Attributes (clearing merging ) and changeable attributes should be
74 explained at a central place.
75 - section titles: "Axes" -> "Axes - module axis" or similar
78 - describe creation and modification (inplace and ``modify by new'') of
83 - names of local and member variables now follow the naming convention of
84 having a _pt suffix when containing lengths in points
86 - names of local and member variables now follow the naming convention of
87 having a _pt suffix when containing lengths in points
88 - enlarge was misspelled as enlarged
89 - renamed _bbox -> bbox_pt
90 - new bbox method center, which returns the coordinates of the center
92 - enlarge and enlarged do no longer interprete unqualified lengths as
95 - unit.cm, unit.t_cm, etc. are no longer sub classes but instances
98 - added new classes page and document for multipage PostScript output
99 - setup.py and distribution:
100 - create siteconfig on install to store position of the share directory
104 - fixed title=None + graph key issue reported by Gabriel Vasseur
105 - graph.axis.painter.plain -> graph.axis.painter.regular
106 (as it was in parts of the documentation already)
107 - changeable-gridattrs-become-None-bug fixed
108 - graph style cutting outside lines (double-)fixed
111 - fixes missing install of the graph and axis directories introduced in 0.6
112 - some minor updates to the faq
116 - reorganisation of the graph structure finished (there might be some
117 small pending issues, but the basic restructuring is done with this release):
118 - graph splitted into several modules in pyx/graph and pyx/graph/axis
119 - painters are using the new attribute scheme including changeable
121 - graph styles rewrite
123 - axis zeropath feature has been removed

127 - symbols + lines -> symbollines; symbols do not allow setting lineattrs,
128 and lines not symbolattrs

130 axis range is set manually etc.)
131 - automatic file key titles
132 - graph.data now also includes the old data module
133 - data.list adds (by default) a line number like data.file
134 (thus regular columns are counted from 1)
136 - added new pathels multilineto_pt and multicurveto which allows to specify
137 a list of points and can thus be much more efficient
138 - internal methods return coordinates in pts
139 - arclentoparam returns only parameters not total length
140 - added path.arclength_pt, path.at_pt, path.begin_pt, path.end_pt (and
141 correspondingly for normpath)
142 - complete refactoring of the normpath class: normpaths now consist of
143 normsubpaths which themselves consist of normlines and normcurves This is
144 much more convenient for any routines working with normpaths.
145 - reversing of closed sub paths does not change the first point of the sub
147 - renamed: arclength -> arclen
148 - renamed: lentopar -> arclentoparam
149 - renamed: glue -> joined
150 - normpath now supports join, the in-place version of joined
151 - path and normpath method raise exception instead of returning None

163 - writeEPSfile deprecates writetofile
164 - internally, write methods are renamed in outputPS
165 - canvas constructor no longer accepts variable argument list but
166 expects a list of attrs as first argument (defaulting to []) and
167 a texrunner as second argument (defaulting to text.defaulttexrunner)
168 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
170 - added inplace add (__iadd__), enlarge and transform methods
171 - callers use inplace add where possible now (yielding a considerable
173 - "undefined" corners of bounding boxes are no longer supported which makes
174 the bounding box operations much more efficient.

178 - removed showbbox argument of epsfile class
180 - default handling of texmessages as in the new attribute scheme
181 - multiple insert bug fixed

402 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
