zip contains both FO and PDF files

For some fonts text underlines may be incorrect. They are positioned upper than
they should be or disappear at all.

Quick investigation of those fonts and FOP sources shows that it depends on
sTypoAscender used in FOP.

Normally sTypoAscender is negative and underlines are positioned correctly in
this case.
If sTypoDecender is positive then text is crossed out instead of underlined. If
it's 0 then underline is invisible.

Attached are FO file and result PDF.
