// You can use set `transforms` to true to return a list of transformation matrices instead of the swept shape. In this case, you can
// often omit shape entirely. The exception is when `closed=true` and you are using the "incremental" method. In this case, `path_sweep`
// uses the shape to correct for twist when the shape closes on itself, so you must include a valid shape.
// .
// By default path sweep objects are anchored to the named anchor "origin" which places the swept object right where you created it.
// Generally you will not want to set an anchor for a swept object, but instead change the path if you want to move it to a different location,
// but can also anchor using VNF anchoring. Usi either `atype="hull"` (the default) or `atype="intersect"` to create anchors based on the
// the object's VNF data. The center of the object is determined based on the `cp` argument and can be "centroid" (the default), "mean" to use the mean of the object,
// or "box" to use the center of the bounding box. For complicated objects you may find it difficult to get useful results from the anchoring
// system, which is designed for an object whose center is inside the object. When using an anchors, confirm that it is in the location you desire.
// Arguments:
// shape = A 2D polygon path or region describing the shape to be swept.
// path = 2D or 3D path giving the path to sweep over
