[dvipdfmx] "mktexpk" is not disabled for fonts loaded by relative path

[Karl Berry]

Hi Shunshaku,

    just want to disable automatic PK font creation? I think this is the
    only "standard" way to do this.

FWIW, I agree with Igor here. The standard behavior in kpathsea is not
to call mktexpk for absolute/explicitly relative fonts. It's not
useful/desirable to do so. I'm somewhat surprised it has not come up
before this.

    Dvipdfmx calls "kpathsea_find_glyph".

How about just checking for absoluteness in dvipdfmx?

if (!kpathsea_absolute_p(...)) {
   ...
   kpathsea_find_glyph(...);
   ...
}

I don't know what complications ensure. There's always something ...

Best,
Karl
