"I am also noticing that zooming is in some cases excessive. Attaching a test
case. Updated the bug title accordingly.

Also, these are all regressions. I still have in the gallery some objects that
were put on the gallery with older versions of LibO (maybe even OO). At that
time, LibO/OO used to create gallery previews where the background transparency
was not evidenced in any way. However, all the present resolution/scaling
issues were absent. All those objects that had been put in the gallery at
ancient times look fine even when I explore the gallery with a recent version
of LibO. Yet, if I take those objects out of the gallery and then I try to put
them back in the gallery, their preview is broken.  Updated the bug title to
make the regression nature of the bug stand out."
