[dvipdfmx] Scaled PK fonts are broken

[Igor Liferenko]

Dear dvipdfmx developers,

Use this test.tex:

    \nopagenumbers
    \font\x=cmr7 scaled\magstep4
    \x Hello World
    \bye

Then process test.dvi using PK fonts:

    T1FONTS=/tmp dvipdfmx x

If you look at the resulting x.pdf, you will see that wrong fonts are used.
Using strace I found out that on my system the file
/usr/share/texlive/texmf-dist/fonts/pk/ljfour/public/cm/dpi600/cmr7.pk
is used. This is wrong. The file should be cmr7.1244pk

Best,
Igor
