Input filters for Bezier editor:

POV bezier_spline
Correctly written SVG (stargate)

Output filters:

Lathe bezier_spline
Prism bezier_spline


Pootrace output is 4 times too many points compared to done by hand.
Some 600 for potrace and 144 by hand. I doubt there are any tracers that can
come close hand-set pnts and handles.

#declare duckp = prism {
linear_sweep
bezier_spline
1.0, //top
0.0, //bottom
144,
