The FcConfig datatype is not exposed to applications; it's entirely 
private to the fontconfig implementation.  If you want to add 
'disabledFonts' to the implementation, you'll need to expose some kind of 
API that uses this datatype, preferably, the FcMatch, FcSort and FcList functions 
would automatically use it to elide 'disabled' fonts from their results so 
that applications wouldn't have to know about it.
