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

26 - contructor should only take a texrunner keyword argument
30 - style and color module:

33 - height -> getheight, ...
35 - TODO: general documentation about attributes, clearing, merging?
36 - TODO: general documentation about changeable attributes?
38 - what about unit.cm() -> unit.cm, ...
39 - maybe we should never convert implicitly into visual/width, etc. lengths
40 - check that we always return the appropriate length, i.e., not
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)

59 - more details in path constructor: allowed pathels, first pathel...
64 Attributes and changeable attributes should be explained in a
66 - section titles: "Axes" -> "Axes - module axis" or similar
71 - reorganisation of the graph structure finished (there might be some
72 small pending issues, but the basic restructuring is done with this release):
73 - graph splitted into several modules in pyx/graph and pyx/graph/axis

122 a texrunner as second argument (defaulting to text.defaulttexrunner)
123 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
125 - added inplace add (__iadd__), enlarge and transform methods
126 - callers use inplace add where possible now (yielding a considerable
128 - "undefined" corners of bounding boxes are no longer supported which makes
