You really must use fontconfig on UNIX though to get the list of
available fonts, font names, etc. though. I don't think shipping a
custom set of fonts with AbiWord is really any good at all for users.
We're getting GTK, Qt, Mozilla, everything on fontconfig, please don't
create exceptions... things are such a mess right now and fontconfig
is such a good idea...

I don't think you want to use Pango for layout, by any means. Well I
don't know AbiWord internals but I can't see how it would make sense.
PangoLayout is just intended for widget labels and GtkTextView.

Owen could say better, but I think what's desired in Pango for
printing is essentially the same thing Pango does for the screen. The
general idea is that you want the same shaping and same font API for
printing that you have for screen display, right.
