-Linear extrusion of 2D shape, with optional twist. The 2d shape is placed in in z=0 plane and extruded into direction offset (a CSG.Vector3D). The final face is rotated twistangle degrees. Rotation is done around the origin of the 2D shape (i.e. x=0, y=0) twiststeps determines the resolution of the twist (should be >= 1), returns a CSG object:
