    Description

      The rect value of the links is not always correct when using PdfLinkModel .

      According to the google code found here:

      https://chromium.googlesource.com/chromium/src/+/2355c635ab7c530c0191c12d4e191861055d696b/pdf/pdfium/pdfium_page.cc

      in the function void PDFiumPage::PopulateAnnotationLinks(), you can see that the values are sometime swapped. The method is a little more complex than Qt is doing this in the function void QPdfLinkModelPrivate::update(), they use also FPDFLink_CountQuadPoints.

      I was able to a patch in qml to obtain the right value, but this one should be done correctly in  QPdfLinkModelPrivate::update().
