Thanks, Philip and Joseph.  The solution proposed by Joseph works fine
although, as pointed out by Philip:

        "There is (to the best of my belief) no specification of rotation in
        the DVI specification, and therefore pure TeX could never accomplish
        such a thing."

...the result is seen in the final PDF output but not in dvi.  In fact, when
opening the simple above example in xdvi, it says:

$ xdvi test
xdvi: Warning: PS code on page 1 may contain rotation, which is not supported by xdvi
xdvi.bin: Warning: Raw Postscript commands on page 1 may be rendered incorrectly.
