Something of a repost, but I’ve learned a bit more on the path to being truly confused.  It appears that boost\geometry\extensions\algorithms\buffer\buffer_inserter.hpp contains some specializations for buffering other shape types?  But I’m out of my depth here… is there an example?  What do I need to do in order to buffer:

a point? 

A linestring? 

A vector of polygons? 

A heterogeneous collections of shapes?

Is this generalization of buffer also going to work as a “deflate” for polygons?

If someone can tell me “include these headers, use these algorithms”, it will help a lot!

Thanks
