 * Import a PDF page, and clone all of its ArtBox, TrimBox, BleedBox, CropBox,

 * and MediaBox entries.

 * Note: You can visualize the page boxes in Acrobat 8 as follows:

 * Choose "Edit, Preferences, General, Page Display, Page Content and

 * Information" and select "Show art, trim & bleed boxes".

 * This setting will create colorized rectangles which indicate the size of the

 * art, trim, and bleed boxes.

 *

 * Required software: PDFlib+PDI/PPS 9

 * Required data: PDF document
