* docs/CHANGES: update to indicate the new FT_Library_Version API

        and the small quality improvement in the Postscript hinter..

        * src/pshinter/pshglob.c: fixed a small bug that created un-even
        stem widths when hinting Postscript fonts. A small fix with pretty
        important improvements in quality of Postscript hinting !!
