[NTG-pdftex] \pdfhorigin / \pdfvorigin broken?

I wonder if there is some automatic translation from 0pt to 1in somewhere... The following \pdfhorigin=0pt \pdfvorigin=0pt \pdfximage page 1 {foo.pdf}% \setbox0=\hbox{\pdfrefximage\pdflastximage}% \pdfpagewidth=\wd0 \pdfpageheight=\ht0 \shipout\box0 \bye gives a shifted output of foo.pdf (by 1in), while \pdfhorigin=1pt \pdfvorigin=1pt \pdfximage page 1 {foo.pdf}% \setbox0=\hbox{\pdfrefximage\pdflastximage}% \pdfpagewidth=\wd0 \pdfpageheight=\ht0 \shipout\box0 \bye gives only a shift by 1pt (as specified)- Something to fix for 1.20 hopefully...
