   shrink: reduce size of postscript graphics

   shrink(input: in, output: out)

   input:  A PostScript program, containing a translate command.
   shrinkp: Parameter file.  The first line contains the scale factor.
   output: A copy of the input with the scale instructions.  A scale
      command is placed immediately after the translate command, so that
      the shrinking occurs toward the zero of the image.

   One often wants to run rsgra to look at a large region of aligned sequence,
   but the normal output won't fit on a page.  By passing the PostScript
   file through this program, one can scale the graphics to something
   that fits on a page.

   0.5  would reduce the size of the image by a factor of 2.
   Note: the 0 is necessary for most Pascal compilers.
