Please describe the problem:
pango_font_description_from_string can recognize "Luxi Serif 8", "Luxi Serif
Bold 8", "Luxi Serif Oblique 8", but not "Luxi Serif Regular 8". fc-list outputs:
$ fc-list | grep Luxi
Luxi Serif:style=Regular
Luxi Serif:style=Bold
Luxi Mono:style=Bold
Luxi Sans:style=Bold
Luxi Sans:style=Regular
Luxi Mono:style=Regular
Luxi Serif:style=Oblique
Luxi Serif:style=Bold Oblique
Luxi Mono:style=Oblique
Luxi Sans:style=Oblique
Luxi Sans:style=Bold Oblique
Luxi Mono:style=Bold Oblique

So I think pango_font_description_from_string should recognize "Luxi Serif
Regular 8", as "Luxi Serif Regular 8" equals to "Luxi Serif 8".
In libgnomeprint, GnomeFont uses "Luxi Serif Regular" style font name, so
function gnome_font_get_pango_description loads font "Luxi Serif Regular"
failed, seems it falls back to "Sans", see libgnomeprint/gnome-font.c.


Steps to reproduce:
1. get libgnomeprint source, go to directory libgnomeprint/tests, run test
programme pango
2. run ./pango -f "Luxi Serif 18" -p files/test.utf8 -o o1.pdf
3. run ./pango -f "Luxi Serif Regular 18" -p files/test.utf8 -o o2.pdf
4. see what's the difference between o1.pdf and o2.pdf
