+\brief Create a squared form buffer around a point
+\ingroup strategies
+\details This strategy can be used as PointStrategy for the buffer algorithm.
+    It creates a square from each point, where the point lies in the center.
+    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.
