The confusing line in the documentation for PangoFcDecoder at \
http://developer.gnome.org/pango/stable/PangoFcFontMap.html#pango-fc-font-map-add-decoder-find-func


is this: "This function saves a callback method in the PangoFcFontMap that will be \
called whenever new fonts are created."

So after I write my decoder, do I have to explicitly create a font? 

For example, Mozilla has a decoder at \
http://people.mozilla.com/~chofmann/l10n/tree/mozilla/gfx/src/gtk/mozilla-decoder.cpp

Is this complete in itself or does mozilla_find_decoder get invoked only when a font \
is explicitly created somewhere in the code? If it needs to be explicitly created, \
does anyone know where in Mozilla code it gets created so that I can use it as an \
example?

Thanks,
-Ferdinand
