Oh, I don't mean that we should exactly follow the `pax` algorithm. I
only mentioned it because it provides a solution.
Isn't it possible to add links with the `pdfmark` operator in the same
way as is already done for annotations by `extractpdfmark`? In
Adobe's pdfmark reference manual (`5150.Pdfmark.pdf`) I see a section
2.1.2 called 'Links', which appears to be exactly what's needed.
