 * Color space for crop marks:
 * Create crop marks which will be visible on all color separations, using the
 * special color "All".
 *
 * Create a CMYK document by loading a CMYK image and create the special
 * color "All". Draw some crop marks with standard vector graphics and
 * output some info text outside of the actual page area (i.e. outside
 * of the CropBox).
 *
 * Test in Acrobat X/XI:
 * Show the MediaBox with Tools, Print Production, More Production,
 * Set Page Boxes, Set to Zero.
 * Choose Tools, Print Production, Output Preview:
 * All elements with color "All" will be visible in all combinations of
 * separation previews.
 * 
 * Required software: PDFlib/PDFlib+PDI/PPS 9
 * Required data: CMYK image
