* a vertex group is the usual source for this.
* \param symmetry_axis: Axis of symmetry, -1 to disable mirror decimate.
* \param symmetry_eps: Threshold when matching mirror verts.

* \note The caller is responsible for recalculating face and vertex normals.
* - Vertex normals are maintained while decimating,
* although they won't necessarily match the final recalculated normals.
* - Face normals are not maintained at all.
