[dvipdfmx] dvipdfmx: how to use PK fonts instead of Type1?

[Igor Liferenko]

Dear Akira,

I works. But only after I comment `f' entries in dvipdfmx.cfg
If default dvipdfmx.cfg is used, this error is given:

Is there an option to override `f' entries from dvipdfmx.cfg without
commenting them?

Thank you,
