PDF doesn't include links inside text elements
In this branch I added a test for PDF output when there is an <a>
link inside <text>
- the test fails. The text outputs the link's textual content just fine, but it's not actually a link in the PDF.
@notriddle may I bother you with this?
(I am not 100% sure if the PDF predicates are able to pick up links on text elements in the same way as they do for other graphical elements - but anyway, if I rsvg-convert the test file by hand to PDF and open it with a viewer, there don't seem to be links in there.)
