//freedesktop.org/bugzilla/show_bug.cgi?id=1518) attachment #1022
    (https://bugs.freedesktop.org/attachment.cgi?id=1022): Add filter
    support to "xlsfonts" that it can filter builtin-, glyph- and/or other
    kinds of printer fonts (controlled by the xp-listfonts-modes attribute
    as described in the CDE DtPrint and Xprint specifications).
