This font, as well as a few other ones from DynaLab _cannot_ return
correct un-hinted glyph outlines _by_design_. That's because they use
some very specific tricks of the TrueType bytecode interpreter
(which isn't run if FT_LOAD_NO_HINTING is used when calling FT_Load_Glyph)

Try loading them with hinting instead, it should solve your problem..
