Looking up fallback/generic versions of fonts (e.g. Times New Roman) #226

At least on Linux looking up the font "Times New Roman" with select_family_by_name doesn't find the fallback font "Tinos".

On the other hand:

fc-match "Times New Roman" finds it
Firefox uses it
Fontconfig::find does too

Is that an intentional limitation? It seems like the method select_generic_font would be able to find it just fine, but isn't exposed.

This is unlikely to be an intentional choice for this library.

I tried to implement this, but it actually results in a kind of opposite problem: select_family_by_name will now always match something, even for nonsense family names. This will kind of break the font-kit internal (CSS) font-selection algorithm used for select_best_match when specifying multiple family names.
