Detailed Description

Let the buffer create rounded ends.

This strategy can be used as EndStrategy for the buffer algorithm. It creates a rounded end for each linestring-end. It can be applied for (multi)linestrings. Also it is applicable for spikes in (multi)polygons. This strategy is only applicable for Cartesian coordinate systems.
