/*
 *  convertFilesToPS()
 *
 *      Input:  dirin (input directory)
 *              substr (<optional> substring filter on filenames; can be NULL)
 *              res (typ. 300 or 600 ppi)
 *              fileout (output ps file)
 *      Return: 0 if OK, 1 on error
 *
 *  Notes:
 *      (1) This generates a PS file for all image files in a specified
 *          directory that contain the substr pattern to be matched.
 *      (2) Each image is written to a separate page in the output PS file.
 *      (3) All images are written compressed:
 *              * if tiffg4  -->  use ccittg4
 *              * if jpeg    -->  use dct
 *              * all others -->  use flate
 *          If the image is jpeg or tiffg4, we use the existing compressed
 *          strings for the encoding; otherwise, we read the image into
 *          a pix and flate-encode the pieces.
 *      (4) The resolution is often confusing.  It is interpreted
 *          as the resolution of the output display device:  "If the
 *          input image were digitized at 300 ppi, what would it
 *          look like when displayed at res ppi."  So, for example,
 *          if res = 100 ppi, then the display pixels are 3x larger
 *          than the 300 ppi pixels, and the image will be rendered
 *          3x larger.
 *      (5) The size of the PostScript file is independent of the resolution,
 *          because the entire file is encoded.  The res parameter just
 *          tells the PS decomposer how to render the page.  Therefore,
 *          for minimum file size without loss of visual information,
 *          if the output res is less than 300, you should downscale
 *          the image to the output resolution before wrapping in PS.
 *      (6) The "canvas" on which the image is rendered, at the given
 *          output resolution, is a standard page size (8.5 x 11 in).

 *  Notes:
 *      (1) If @fp != NULL, this function compares two golden files to
 *          determine if they are the same.  If @fp == NULL, this is a
 *          "generate" operation; don't do the comparison.
 *      (2) This function can be called repeatedly in a single reg test.
 *      (3) The value for @success is initialized to TRUE in the reg test
 *          setup before this function is called for the first time.
 *          A failure in any file comparison is registered as a failure
 *          of the regression test.
 *      (4) The canonical format of the golden filenames is:
 *             /tmp/<root of main name>_golden.<index>.<ext of localname>
