Compatibility with OpenPDF as alternative to iText 2.1.7 [SPR-16107]

[spring-projects-issues]

Juergen Hoeller opened SPR-16107 and commented

OpenPDF is an actively maintained, liberally licensed fork of 2009's iText 2.1.7 (which turned AGPL afterwards): https://github.com/LibrePDF/OpenPDF

Since our AbstractPdf(Stamper)View classes work fine with OpenPDF as well, let's explicitly declare compatibility there.
