Description

A commit of code modification made by Safe Software:

When buffering, we previously filtered out points that were some distance away from the original geometry. This value was set as 98% of the buffering distance. The problem with that was, at large distances, artifacts arise because they don't get filtered as they should.

We've made a code change here to improve the filtering of artifacts when doing a single sided buffer, especially for larger values. The patch is attached and like before, we want to allow some time for feedback before committing.
