 * Control NexPress trays:

 * For NexPress digital color printing machines, create some special kind of

 * annotations to control the input tray.

 *

 * Use the "custom" option of create_annotation() to create a "Stamp" annotation

 * with NexPress-specific custom extensions.   

 * The "P" in "PDF" means "Portable", which excludes the use of device-specific

 * parameters such as tray control. This technique is not really in the spirit

 * of portable PDF documents, but NexPress digital printing machines expect it

 * this way nevertheless.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 9

 * Required data: none
