 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.
