        Remove ClassDef->Defined field.  This is the comment accompanying it:

          The `Defined' field is not defined in the OpenType specification
          but apparently needed for processing fonts like trado.ttf: This
          font refers to a class which contains not a single element.  We
          map such classes to class 0.

        The comment is correct that trado.ttf (MS Traditional Arabic) uses
        such classes.  However, in my testing I couldn't identify any
        problems with the font if the special handling is removed.  I also
        processed as many fonts as I could get my hand on and trado.ttf was
        the only not-totally-broken font hitting the special-case code.
        DejaVu fonts hit it too, but I'm sure they do not require the
        special-handling code.  Most probably, that code introduces bugs
        in them.

        The special-casing was consuming lots of memory.  EIGHT MEGABYTES
        for loading DejaVu Sans!  While this could be complete fixed, I
        decided to remove the special-handling code altogether.  I don't
        think it will make any real difference, and if it does, we'll fix
        fonts.  Such hacks will not be in harfbuzz-ng anyway.

        Bug originally reported by nsf.
