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

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