I'd prefer to keep the agg specific code inside the
AGGMapserverRenderer object, in the renderRasterGlyphs member
function, what do you think?

yes and no:
* the code shouldn't be segfaulting
* raster fonts are kind of a hack, and characters above 127 depend on
the encoding, so even if the >127 chars were supported, there'd be
only a slim chance that they corresponded to the encoding you where
looking for
