Enforce a minimum value for the Offset Curve Quadrant Segments (a value of 8 works well). This fixes an issue with offset curve artifacts appearing when very small QuadSeg values are used. This is due to the need to have a relatively circular end cap in the associated buffer polygon.
At some future point it might be possible to enforce the minimum QS value for just the end caps, since using a small at joins should not cause a problem.
