To convert from a pure spline to a lathe or prism spline, you'd specify
which two coordinate axes you want, using the normal x/y/z r/g/b/f/t
symbols.  Natural cubic splines would be converted to catmull-rom cubics,
and a warning message printed.  I haven't figured out what the syntax for
going from objects to pure splines would be yet.

e.g. prism{ MyLinearSpline x,y linear_sweep 0, 1} uses the x and y
coordinates of the spline from MyLinearSpline as the shape of the prism.
