5 - fix intersection (see test/functional)
7 - make dash length available

57 Changeable attributes should be explained at a central place.
59 - linealign and circlealign
60 - need to be redone anyway
62 styles: document what data name the styles accept (require). Try also to be more
63 userfriendly and not to describe immediately the internals of the implementation:
64 (see e.g. class.style.symbol)
65 - include the deformer docu somewhere in path

661 - correct arrow template calculation for very short paths
665 - new easy to use example generation (will hopefully lead to nice examples)
667 - new module for handling of convex polygons (taken out of the graph module)
669 - new module containing a collection of helper functions (taken out of the graph module)
670 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
672 - new module: a new and preferable integration of TeX/LaTeX
674 - strip glyphs from pfa/pfb-fonts
675 - there is a C implementation taken from pdftex
676 - fallback solution via an external program (pfb2pfa)
678 - (partial) C binding to libkpathsea
679 - fallback solution via an external program (kpsewhich)
681 - removed some code duplication (various axis painters)
682 - use text module instead of the obsolete tex module
683 - allow for tailing zeros of automatic generated labels
684 - allow for missing data in bar graphs -> skipmissing parameter
685 - remove the support for variables given as keyword arguments in data constructor
686 - use context instead of extern for extern variables and functions
687 - graph keys; titles in data/function/etc.
689 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
690 - all length classes have now by default a quantifier 1 (instead of 0), such that,
691 for instance, 5*unit.t_cm() == unit.t_cm(5)
692 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
693 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
695 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
696 for internal purposes.
697 - the bbox constructor now accepts user lengths in the constructor.
698 - new methods height, width, top, bottom, left, right
699 - ll & ur ???, what about ul and lr -> ugly!
700 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
701 - output HiResBoundingBox
702 - never reduce bbox upon output
704 - new constructor signature, more in line with rest of PyX:
705 epsfile(x, y, filename, **additional_args)
707 - removed additional column support in addcolumn; removed _addcolumn
708 - line reduction for datafile like the every parameter in gnuplot
710 - new way of PS prolog generation that writes only necessary parts
711 - added support for patterns
712 - canvas.insert() now supports arguments
713 - bbox of canvas can be specified in writetofile command explicitely
714 - writetofile does not return self anymore
715 - arrow template now uses intersection with circle to get size right
716 (as per a suggestion by Michael Schindler)
719 - changed the handling of extern functions and all variables
721 - gradient renamed to palette
723 - problem with sizefile on windows (tex module)
724 - allow for strings in graphxy's width and height; allow for width only (graph module)
725 - disable rating for labelattrs equals None (graph module)
726 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
727 - traverse when adding functions as arguments of operators (mathtree module)
728 - allow for extern functions in addcolumn (data module)
729 - just one common place for the version number
730 - fix incorrect exception name MathError (path module)
731 - prevent double return of intersections for closed sub paths
736 - allow division of length by numbers
738 - new transformation: slant
739 - renamed all trafo methods to use the participle (i.e translate->translated)
740 - the name of all trafo subclasses are verbs (i.e. translation->translate)
742 - mark class renamed to symbol
743 - (text-)box distance measurement
744 - moved axis partitioning to axis and axis painter
745 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
747 - baraxis, baraxispainter, and bar style
749 - previously named datafile module
750 - class "_datafile" renamed to class "data"
751 - class sectionfile added
754 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
757 - deferred to Version 0.3
758 - running TeX "on the fly" is basically implemented
760 - transformation bug (#624068, trafo module)
761 - canvas transformations (canvas module???)
762 - textbox alignment (graph module)
763 - return linewidth upon calculation with linewidths (unit module)
764 - allow column number variables with several digits
766 - british and american spellings (color module, graph module)
767 - small logo modifications
