[LDPE] 1.8.57 Released (CC BY 4.0, subfile selections, file location for linked inlining)

[Nils Schmidt]

When the source lines come from an offset subpart, Ytruder "symmetry across plane" doesn't create the correct result.
See this screen capture:
The first try directly uses lines from the offset subpart and fails, the second one first copies the lines and produces the desired result.
Files attached to reproduce issue.
(projection on plane also fails)

Thanks! I created issue #915.

edit: This will be solved with version 1.8.59.
