0.13d did it the same as rc2; all other versions I tried (1.00b
and 1.11a) give a different result. The question is: What is
right?

I presume that in TeX one would do 
-------------
\nopagenumbers
\parindent=0pt

\magnification=500

%\pdfhorigin=1truein
%\pdfvorigin=1truein

\hsize=210truemm
\vsize=297truemm

\hrule width 25.4truemm height 10truemm

With TeX (and pdfTeX when writing dvi) the origin is not moved;
but this IMHO comes from the fact that the origin in dvi is
always at (1in/1in). Which is not true for pdf output.

It seems reasonable to assume the same for pdf as for dvi: The
origin is not moved by \magnification, i.e. the behaviour when
producing pdf and dvi is the same. This would mean that rc2 is
buggy.

Whatfor are \pdf*origin actually used? A grep on ctan/macros
finds only occasions where it's set to 1truein.
