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 - use csv module (new in 2.3)
20 - Check for "inf" and "nan" in datafiles.
21 (When plotted, the graph does not complain, but the postscript will be broken)
23 - finish multi page PostScript output
24 - contructor should only take a texrunner keyword argument
28 - style and color module:
29 - support modification of existing styles via __call__
31 - height -> getheight, ...
33 - maybe we should never convert implicitly into visual/width, etc. lengths
35 - might be moved into the graph
36 - perform calc by means of Python itself (see eval code in graph.data, but
37 we should use compiled code instead of eval)
39 - think hard about different paths in decoratedpath class
40 - adjust parameters of cycloid and smoothed
41 AW: I suggest to use cycloid with default curvesperloop=5.
43 - support single-character mode
45 - arclentoparam should raise an exception when the arclen is out of range
46 - it seems to be, that epsilon is a feature of normsubpath;
47 AW: Why is there (also) a self.epsilon?
48 JL: What class does self refer to?
49 AW: I'm sorry for not being precise. Both, normpath and normsubpath do
50 have an epsilon. I'm not sure if we should do that (its slightly
51 confusing). In normpath._findsubpath we should refer to the
52 epsilons of the subpath. The only usage of epsilon left in normpath
53 is in the constructor and in append (BTW -- we do have some code
54 dublication here). A possibility would be to add a keyword-argument
55 epsilon to append. The point is, that I would like to get rid of
56 self.epsilon, where self is a normpath instance ...
57 - How about normpathel.begintrafo() and normpathel.endtrafo()?
59 AW: May I be able to change your rank to -0 when comming up with a
60 profile for typical use cases of (new style) boxes? We do have
61 begin, at and end for the normpathel's. Why is the analogous for
62 normpathel.trafo a bad idea?
64 - what should we do for palette when only one entry
69 - more details in path constructor: allowed pathels, first pathel...
74 Attributes (clearing merging ) and changeable attributes should be
75 explained at a central place.
76 - section titles: "Axes" -> "Axes - module axis" or similar
79 - describe creation and modification (inplace and ``modify by new'') of
84 - names of local and member variables now follow the naming convention of
85 having a _pt suffix when containing lengths in points
87 - names of local and member variables now follow the naming convention of
88 having a _pt suffix when containing lengths in points
89 - enlarge was misspelled as enlarged

118 - painters are using the new attribute scheme including changeable

129 axis range is set manually etc.)
130 - automatic file key titles
131 - graph.data now also includes the old data module
132 - data.list adds (by default) a line number like data.file
133 (thus regular columns are counted from 1)
135 - added new pathels multilineto_pt and multicurveto which allows to specify
136 a list of points and can thus be much more efficient
137 - internal methods return coordinates in pts
138 - arclentoparam returns only parameters not total length
139 - added path.arclength_pt, path.at_pt, path.begin_pt, path.end_pt (and
140 correspondingly for normpath)
141 - complete refactoring of the normpath class: normpaths now consist of
142 normsubpaths which themselves consist of normlines and normcurves This is
143 much more convenient for any routines working with normpaths.
144 - reversing of closed sub paths does not change the first point of the sub
146 - renamed: arclength -> arclen
147 - renamed: lentopar -> arclentoparam
148 - renamed: glue -> joined

165 expects a list of attrs as first argument (defaulting to []) and
166 a texrunner as second argument (defaulting to text.defaulttexrunner)
167 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
169 - added inplace add (__iadd__), enlarge and transform methods
170 - callers use inplace add where possible now (yielding a considerable
172 - "undefined" corners of bounding boxes are no longer supported which makes
173 the bounding box operations much more efficient.

401 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
403 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
404 for internal purposes.
