// 'main' takes in .so files for two versions of FT, the character size, and
// a font directory. It uses 'bitmap' and 'murmur3' to compare hashes for all
// glyphs in the font, using the base and test FT libraries, then renders
// differing glyphs as PNGs. A webpage is generated with a table of these
// glyphs.
