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

[Igor Liferenko]

Hi all,

I need to use PK fonts instead of Type1. dvipdfmx does not allow to do this.
Is it possible to add an option to use PK fonts?

Consider this x.tex:

    hello \bye

Process it with tex and then with dvipdfmx:

    $ dvipdfmx -vv x
    <FONTMAP:/var/lib/texmf/fonts/map/pdftex/updmap/pdftex.map><FONTMAP:/var/lib/texmf/fonts/map/dvipdfmx/updmap/kanjix.map><FONTMAP:/usr/share/texlive/texmf-dist/fonts/map/dvipdfmx/ckx.map>x
-> x.pdf

We see that cmr10.pfb is used. Now comment all lines beginning with
`f' in dvipdfmx.cfg
and run dvipdfmx again:

    $ dvipdfmx -vv x
    x -> x.pdf

We see that "Type1" font is used again. Now we remove cmr10.pfb and run
dvipdfmx again:

    $ dvipdfmx -vv x
    x -> x.pdf

Now we see that PK font is used, as desired.

How to achieve the same effect without removing cmr10.pfb?
