Sample ODG

This is a skia bug, thus it can be reproduced in Windows, or via the gen backend in Linux. No issue when not using skia.

The attached ODG was created by saving attachment 99486 [details] (an MS Publisher file) from bug 69080 as ODG. The format is irrelevant, but the PUB file requires bug 122660's fix to open correctly.

Open the sample, and check the image on the second page.

=> The image is blurry, and possibly incorrectly placed/sized (depending on the zoom level).

This is a regression, even when using the skia backend, as it was fine ~2 weeks ago, and exhibits both issues in LO (7daab7859f3b5b4297c45ac1631c68387192a962).
It regressed in two steps, bibisected using repo bibisect-linux-64-6.5. Adding CC: to Luboš Luňák.

1. Image is blurry.
