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 ...
62 - How about normpathel.begintrafo() and normpathel.endtrafo()?
64 AW: May I be able to change your rank to -0 when comming up with a
65 profile for typical use cases of (new style) boxes? We do have
66 begin, at and end for the normpathel's. Why is the analogous for
67 normpathel.trafo a bad idea?
69 - what should we do for palette when only one entry
74 - more details in path constructor: allowed pathels, first pathel...
79 Attributes (clearing merging ) and changeable attributes should be
80 explained at a central place.
81 - section titles: "Axes" -> "Axes - module axis" or similar
84 - describe creation and modification (inplace and ``modify by new'') of
89 - names of local and member variables now follow the naming convention of
90 having a _pt suffix when containing lengths in points
92 - names of local and member variables now follow the naming convention of
93 having a _pt suffix when containing lengths in points
94 - enlarge was misspelled as enlarged
95 - renamed _bbox -> bbox_pt
96 - new bbox method center, which returns the coordinates of the center
98 - enlarge and enlarged do no longer interprete unqualified lengths as
101 - unit.cm, unit.t_cm, etc. are no longer sub classes but instances
104 - added new classes page and document for multipage PostScript output
108 - fixed title=None + graph key issue reported by Gabriel Vasseur

110 (as it was in parts of the documentation already)
111 - changeable-gridattrs-become-None-bug fixed
112 - graph style cutting outside lines (double-)fixed
115 - fixes missing install of the graph and axis directories introduced in 0.6
116 - some minor updates to the faq

121 small pending issues, but the basic restructuring is done with this release):
122 - graph splitted into several modules in pyx/graph and pyx/graph/axis
123 - painters are using the new attribute scheme including changeable
125 - graph styles rewrite
127 - axis zeropath feature has been removed

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

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

182 - removed showbbox argument of epsfile class

405 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
406 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
408 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
409 for internal purposes.
410 - the bbox constructor now accepts user lengths in the constructor.
411 - new methods height, width, top, bottom, left, right
