* Rotated text:
* Create rotated text lines and Textflows which do not run horizontally,
* but at some angle
*
* Three text lines are generated which are oriented to the west, east, or
* south. A text line is rotated by 30 degrees. A Textflow is created which
* is rotated by 30 degrees. A Textflow is generated with a rotation of 30
* degrees and an orientation to the west.
*
* Required software: PDFlib/PDFlib+PDI/PPS 9
* Required data: none
