 * Create local link in rotated PdfPCell in iTextSharp

 * <p>
 * This is the equivalent Java code for the C# code in the question. Indeed, this code
 * also gives rise to the broken result. The cause is simple: Normally iText does not
 * touch the current transformation matrix. So the chunk link creation code assumes the
 * current user coordinate system to be the same as used for positioning annotations.
 * But in case of rotated cells iText does change the transformation matrix and
 * consequently the chunk link creation code positions the annotation at the wrong
 * location.
