651 - graph style cutting outside lines (double-)fixed
655 - fixes missing install of the graph and axis directories introduced in 0.6
656 - some minor updates to the faq
661 - reorganisation of the graph structure finished (there might be some
662 small pending issues, but the basic restructuring is done with this release):
663 - graph splitted into several modules in pyx/graph and pyx/graph/axis
664 - painters are using the new attribute scheme including changeable
666 - graph styles rewrite
668 - axis zeropath feature has been removed

675 axis range is set manually etc.)
676 - automatic file key titles

711 expects a list of attrs as first argument (defaulting to []) and
712 a texrunner as second argument (defaulting to text.defaulttexrunner)
713 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
715 - added inplace add (__iadd__), enlarge and transform methods
716 - callers use inplace add where possible now (yielding a considerable
718 - "undefined" corners of bounding boxes are no longer supported which makes
719 the bounding box operations much more efficient.
