this seems to be a bug in old dvipdfm 0.13.2c. My mpost testfile is
this:

beginfig(1)
a := 150;
draw unitsquare scaled a;
draw origin --(a,a);
draw (0,a) --(a,0mm);
endfig;
end

The latex testfile is:

\documentclass{article}
\pagestyle{empty}
\usepackage{graphicx}
\begin{document}
\includegraphics{xx.eps}
\end{document}

then do latex and dvipdfm. And the /BBox of the image is /BBox [0 0 2384
3370], which is wrong, as the pen moves to 0 0 so half of the line is
negative and therefore clipped. In dvi still everything is ok.

Ha, and with dvipdfmx-20061211 it's fine! The /BBox is correct. This is
part of TeX Live 2007. Just use dvipdfmx, and you will be happy...
