X, Y, Z are parameters for the following postgis equation. The default values are chosen according to the size of the original geometry to give a slighty bigger geometry, without too many nodes.

Note that:- X > 0 will give a polygon bigger than the original geometry, and guaranteed to contain it.
- X = 0 will give a polygon similar to the original geometry.
- X < 0 will give a polygon smaller than the original geometry, and guaranteed to be smaller.
