[texhax] Landscape orientation with plain TeX

correct, though lscape could (i expect) be used with plain, if you
also load the plain version of the latex graphics package.

however, this may not be the best way forward.  lscape's code does

  \clearpage % i.e., \vfill\eject
  <set page dimensions for landscape>
  <set up output routine to rotate \box255 by 90 degrees>

at the start, and

  \clearpage
  <restore output routine>
  <restore page dimensions>

these are strightforward enough ideas, but it would take me some time
to work them out since i don't program the plain output routine much
(if at all).  hope it helps, anyway.
