[Fontconfig] problem with some font styles/weights

[Ernest Adrogué]

Hi,

I noticed that fontconfig gets confused when finds a
family of fonts with styles like "expanded" or "condensed",
or weights as "book". In such circumstances only one of the
styles/weights can be selected, and the others remain
completely unusable. I'm not a hacker, but I guess that it
is not very difficult to fix this; if fontconfig can
distinguish "light" from "normal", then it could do so with
"book", "medium condensed", or whatever as well.

This is the only "obstacle" (I don't know the English word)
I find in fontconfig.

Many thanks to the developers for their work.
