 //   Spin is specified with the `spin` argument in most shape modules.  Specifying a scalar `spin`
 //   when creating an object will rotate the object counter-clockwise around the Z axis by the given

 //   axes by the number of degrees in each component of the vector.  Spin is always applied after

 //   you might think of intuitively as spinning the shape.  To do that, apply `zrot()` to the shape before anchoring.

 //   Orientation is specified with the `orient` argument in most shape modules.  Specifying `orient`
