Detailed Description

Let the buffer create rounded corners.

This strategy can be used as JoinStrategy for the buffer algorithm. It creates a rounded corners around each convex vertex. It can be applied for (multi)linestrings and (multi)polygons. This strategy is only applicable for Cartesian coordinate systems.
