What do you mean by that? AFAICS they are pretty much used. We call
GlobalParams::setupBaseFonts from init_xpdf_core (in
pdfedit-core-dev.cc) and all available fonts are then stored in
GlobalParams::displayFonts hash table which is used by PreScanOutputDev
and SplashOutputDev (check for getDisplayFont).

You know at least that fonts cannot be found when you cannot see
anything or missing text on your screen. This is the way how I found out
that setupBaseFonts has to be called during xpdf initialization back
then when one of the xpdf update changed this behavior IIRC.
