        TrueType font support. These functions allow PPR to generate
        PostScript fonts from Microsoft compatible TrueType font files.

        The functions in this file do most of the work to convert a
        TrueType font to a type 3 PostScript font.

        Most of the material in this file is derived from a program called
        "ttf2ps" which L. S. Ng posted to the usenet news group
        "comp.sources.postscript". The author did not provide a copyright
        notice or indicate any restrictions on use.
