For out project (lilypond) it's quite important to have fontconfig
return only scalable fonts.  Perhaps it makes sense to add a new
function to fontconfig which controls that?

I can try to circumvent the issue (this is, using FreeType stuff to
test whether a font is scalable), but then it would be necessary that
fontconfig returns a list of fonts which exactly fit the search
pattern so that I can iterate its elements (or perhaps fontconfig
itself provides such an iterator).  Is this possible?
