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

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