6 - 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)

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