Don't do two hash lookups in loadGlyphs()
loadGlyphs() has a big impact on text rendering speed on X11. Removing
the uneeded hash lookup makes this function go twice as fast, as it in
the common case (where the glyphs are already cached) the hash lookups are
100% of the running time of the function.
