* PDF/X-4 starter:
* Create PDF/X-4 conforming output with layers and transparency
*
* A low-level layer is created for each of several languages, as well
* as an image layer.
*
* The document contains transparent text which is allowed in
* PDF/X-4, but not earlier PDF/X standards.
*
* Required software: PDFlib/PDFlib+PDI/PPS 10
* Required data: font file, image file
