bug: inserting rotated pages to another document messes up link coordinates

[mahlzahn]

Description of the bug

Copying pages togther with links from one document to another leads to wrong coordinates in the copied document, see reproducer below.

How to reproduce the bug

import pymupdf

document = pymupdf.Document()
document.new_page()
document[0].set_rotation(90)
document[0].insert_link({'kind': 2, 'from': pymupdf.Rect(10, 20, 40, 60), 'uri': 'https://example.org'})

document_copy = pymupdf.Document()
document_copy.insert_pdf(document, links=True)

print('orig:', *(l['from'] for l in document[0].get_links()))
print('copy:', *(l['from'] for l in document_copy[0].get_links()))

prints

orig: Rect(782.0, 10.0, 822.0, 40.0)
copy: Rect(802.0, 782.0, 832.0, 822.0)

PyMuPDF version

Possible workaround:

document_copy2 = pymupdf.Document()
document_copy2.insert_pdf(document, links=False)
for i in range(len(document)):
    document_copy2[i].set_rotation(0)
    for link in document[i].get_links():
        link['from'] = link['from'].transform(document[i].derotation_matrix)
        document_copy2[i].insert_link(link)
    document_copy2[i].set_rotation(document[i].rotation)
print('copy2:', *(l['from'] for l in document_copy2[0].get_links()))

But, it is probably still wrong for scaled or otherwise transformed documents.

Thank you for providing the description and the reproducer for the coordinate issue in PyMuPDF #4958.
