inkslip-serif.ttf — the font the signer's PDF copy is printed in.

It is a subset of FreeSerif from GNU FreeFont (version 0412.4273, the 2012
release packaged by Debian as fonts-freefont-ttf), cut down to the scripts a
waiver needs: Latin with its accented letters, Greek, Cyrillic, Hebrew and
Arabic (with the Arabic presentation forms), punctuation and currency signs.
The subset was made with fontTools' pyftsubset; no glyph was redrawn.
