PATCH: Fix for printing symbols and variable width underlining.

[Martin Sevior]

Hi,
        I found the Adobe "redbook" on Postscript in my colleagues office
and have been able to fix a couple of printing bugs on abiword. These were
the variable width underlining (you have issue "stroke" after the ML macro)
and printing symbol and dingbat fonts. For some reason that I don't
understand, every font was declared as a Latin1. Why? The macro "LAT" does
this. I removed it and I see no difference in the quality of regular fonts
but now "symbol" and "dingbat" fonts are printed.

The diff from my patched source (the one I sent in earlier)
follows. Just a couple of simple patches to xap_UnixPSGraphics.cpp  in
directory:
