728 - correct arrow template calculation for very short paths
732 - new easy to use example generation (will hopefully lead to nice examples)
734 - new module for handling of convex polygons (taken out of the graph module)
736 - new module containing a collection of helper functions (taken out of the graph module)
737 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
739 - new module: a new and preferable integration of TeX/LaTeX
741 - strip glyphs from pfa/pfb-fonts
742 - there is a C implementation taken from pdftex
743 - fallback solution via an external program (pfb2pfa)
745 - (partial) C binding to libkpathsea
746 - fallback solution via an external program (kpsewhich)
748 - removed some code duplication (various axis painters)
749 - use text module instead of the obsolete tex module
750 - allow for tailing zeros of automatic generated labels
751 - allow for missing data in bar graphs -> skipmissing parameter
752 - remove the support for variables given as keyword arguments in data constructor
753 - use context instead of extern for extern variables and functions

760 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
762 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
763 for internal purposes.
764 - the bbox constructor now accepts user lengths in the constructor.
765 - new methods height, width, top, bottom, left, right
766 - ll & ur ???, what about ul and lr -> ugly!

771 - new constructor signature, more in line with rest of PyX:
772 epsfile(x, y, filename, **additional_args)

803 - allow division of length by numbers
805 - new transformation: slant
806 - renamed all trafo methods to use the participle (i.e translate->translated)
807 - the name of all trafo subclasses are verbs (i.e. translation->translate)
