Thanks for the feedback!  This solution is perfectly workable.
However, I had to change the -9p to -8.8p (which is the
aspect ratio of the image times 10p) to get the baseline of
the text to the right of the image to be aligned with the
text on the left.

Interestingly, I also get a vertical shift if I wrap the sequence
\v'...'\X'...' in \Z'...' which is supposed to restore the
horizontal and vertical position after outputting the contents.
Does that mean that the pdfpic special does not restore the
graphics state (with q/Q) after inserting the image file?
In that case there might be a discrepancy between what troff
and gropdf consider to be the current output position.
