PDF test case (compressed to fit in 4M)

As reported in https://gitlab.gnome.org/GNOME/evince/issues/719

Steps to reproduce:
- open the following pdf file
https://osug-owncloud.ujf-grenoble.fr/index.php/s/xvB0t7SFUNC842P
- go to a zoom level of 100%
=> strange vertical lines appear in the figure
- open the same file in mupdf
=> the display of the figure is better, without vertical lines

Output of pdftocairo

The issue is reproducible with Poppler master (6b37df791), with pdftocairo but not pdftoppm.
