Bad and good visualizations

When fixing Bug 37246, I have found that test PDF contains unneeded strokes with incorrect colors.
Investigation of this bug led me to commit
http://cgit.freedesktop.org/libreoffice/core/commit/?id=128adf7e5c06fff378c8d72b44ec4be1e462984f
and to Bug #109708 from OpenOffice:
https://issues.apache.org/ooo/show_bug.cgi?id=109708

I've tried to remove this commit and see what happens.
Surprisingly, existing negative effects were gone, while new ones was not appearing.

In comments to Bug #109708 we can find out that more correct solution to problem is to "Change the way of displaying objects"
https://wiki.openoffice.org/wiki/User:Joekidd/OpenOffice.org/Internship/PDFImport/Tasks/Issue109708

Which exactly, I suppose, was done.

Problematic and normal rendering you can see at attached image.
Both PDF used for testing are also attached.
