Detailed Description

Create a circular buffer around a point.

This strategy can be used as PointStrategy for the buffer algorithm. It creates a circular buffer around a point. It can be applied for points and multi_points, but also for a linestring (if it is degenerate, so consisting of only one point) and for polygons (if it is degenerate). This strategy is only applicable for Cartesian coordinate systems.
