- fix insertion of a zero length path when the whole line is outside
the valid axis range (reported by Marko Vendelin)

(as it was in parts of the documentation already)

- fixes missing install of the graph and axis directories introduced in 0.6
- some minor updates to the faq
0.6 (2004/03/30):
- graph module:
- reorganisation of the graph structure finished (there might be some
small pending issues, but the basic restructuring is done with this release):

- painters are using the new attribute scheme including changeable
- graph styles rewrite
- graph data rewrite
- axis zeropath feature has been removed
- mergelabels removed; linpart doesn't have a label argument anymore
- names and texts removed from baraxis
- iteration on graph style, when it is used several times in the same graph
- symbols + lines -> symbollines; symbols do not allow setting lineattrs,
and lines not symbolattrs
- manual line clipping (do not include unneeded line segments when the
axis range is set manually etc.)
- automatic file key titles
- now also includes the old data module
- data.list adds (by default) a line number like data.file
(thus regular columns are counted from 1)

a list of points and can thus be much more efficient
- internal methods return coordinates in pts
- arclentoparam returns only parameters not total length
- added path.arclength_pt, path.at_pt, path.begin_pt, path.end_pt (and
correspondingly for normpath)

normsubpaths which themselves consist of normlines and normcurves This is
much more convenient for any routines working with normpaths.

constructor and no longer in arguments of path and normpath methods

alternatively accept an arc length

- set, draw, stroke and fill no longer return self, i.e., the canvas, but None
- bbox module:
- added inplace add (__iadd__), enlarge and transform methods
- callers use inplace add where possible now (yielding a considerable
- "undefined" corners of bounding boxes are no longer supported which makes
the bounding box operations much more efficient.
- connnector module:
- renamed _xxx -> xxx_pt
- epsfile module:
- removed showbbox argument of epsfile class
