+----------------------------------------------------
+This tests correct functioning of multi-page delete
+----------------------------------------------------
+Create a PDF in memory with 100 pages with a unique text each.
+Also create a TOC with a bookmark per page.
+On every page after the first to-be-deleted page, also insert a link, which
+points to this page.
+The bookmark text equals the text on the page for easy verification.
+
+Then delete some pages and verify:
+- the new TOC has empty items exactly for every deleted page
+- the remaining TOC items still point to the correct page
+- the document has no more links at all
