harfbuzz creator made https://github.com/behdad/glyphy/ https://github.com/behdad/glyphy/ which i integrated into GTK a while back (but we don't ship currently, because we still do the bitmap stuff). the bitmap stuff still has major drawbacks though, like maintaining grid alignments and pixel boundaries where as this stuff (mostly) goes away using glyphy. still work to be done around hinting though (hence not merged).
