This node sets the selected (or all) splines in curve to a chosen target spline type. Poly, Bezier, and NURB splines can be converted to any of the other types. This is meant to be a building block node, useful in many procedural situations. In the future the node could be optimized with multi-threading, or by avoiding copying in many cases, either by retrieving the curve for write access or by passing the raw vectors to the new splines where possible.
