             which are defined to be 1/72 inch.  The printer will
             only see the size of the image in pts, through the
             scale and translate parameters and the affine
             transform (the ImageMatrix) of the image.
      (6) To render multiple images on the same page, set
          endpage = FALSE for each image until you get to the
          last, for which you set endpage = TRUE.  This causes the
          "showpage" command to be invoked.  Showpage outputs
          the entire page and clears the raster buffer for the
          next page to be added.  Without a "showpage",
          subsequent images from the next page will overlay those
          previously put down.
      (7) For multiple pages, increment the page number, starting
          with page 1.  This allows PostScript (and PDF) to build
          a page directory, which viewers use for navigation.

          print binary PS files.
      (3) For the first image written to a file, use "w", which
          opens for write and clears the file.  For all subsequent
          images written to that file, use "a".
      (4) To render multiple images on the same page, set
          endpage = FALSE for each image until you get to the
          last, for which you set endpage = TRUE.  This causes the

          the entire page and clears the raster buffer for the
          next page to be added.  Without a "showpage",
          subsequent images from the next page will overlay those
          previously put down.
      (5) For multiple images to the same page, where you are writing
          both jpeg and tiff-g4, you have two options:
           (a) write the g4 first, as either image (maskflag == FALSE)
               or imagemask (maskflag == TRUE), and then write the
               jpeg over it.
           (b) write the jpeg first and as the last item, write
               the g4 as an imagemask (maskflag == TRUE), to paint
               through the foreground only.
          We have this flexibility with the tiff-g4 because it is 1 bpp.
