Char paths contain cubic splines.  The control points for these splines
may be outside of the character bounding box.  They are however, part of the
path that is used to compute the bounding box by pathbbox.  Flattenpath
reduces them to straight lines such that the coordinates lie within the 
bounding box, thus allowing a true computation of the letter bounding box.
