57 Changeable attributes should be explained at a central place.
59 - linealign and circlealign
60 - need to be redone anyway

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

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