patch -- fix xft in gnome build

[Joaqu�n Cuenca Abela]

Now at least it compiles.

Last time I tried to print something with truetype fonts using
gnome-print, it was segfaulting, so Martin, if you want to fix it double
check first if it's working in the non xft build.  I've just tested to
preview a simple doc using Times New Roman, and it has segfaulted. 
Don't know if it's our fault, or gnome-print fault, but I don't think
that xft is making a difference here.

Cheers,

P.S.: getAscender sometimes is used to get the ascender, sometimes to
get the bbox ury.  I've not fixed that mess, and I will probably not fix
it until I take a look at removing layout units and getting 100%
WYSIWYG.  So by now, live with it :)
