'''<indexterm><primary>strategy</primary></indexterm><indexterm><primary>buffer</primary></indexterm><indexterm><primary>join_miter</primary></indexterm>'''
Let the buffer create sharp corners. 

[heading Description]
This strategy can be used as JoinStrategy for the buffer algorithm. It creates a sharp corners around each convex vertex. It can be applied for (multi)linestrings and (multi)polygons. If corners are sharp by themselves, the miters might become very long. Therefore there is a limit (miter\u005flimit), in terms of the used distance, which limits their length. The miter is not changed to a bevel form (as done in some other software), it is just adapted to the specified miter\u005flimit but keeps its miter form. If the buffer distance is 5.0, and the miter limit is 2.0, generated points will be located at a distance of at most 10.0 (2*5) units. This strategy is only applicable for Cartesian coordinate systems.
