`ass_face_set_size' requests a font with zero dimensions, which is
invalid for `FT_Request_Size': it has no code to set defaults for
zero-valued arguments (contrary to `FT_Set_Char_Size').

FreeType shouldn't crash (I've just added a guard to the git
repository), but the above is not valid code and only works by
accident for older FreeType versions.
