Oops, sorry, there actually *is* bytecode in the glyphs and it works,
but only in v35 mode of the bytecode interpreter.  Because FreeType
can't detect the trickyness automatically, v40 is applied by default,
causing the bad rendering results.

Toshiya-san, do you think it makes sense to add this subsetted font's
cvt/prep/fpgm checksums to FreeType?
