-/* Given a function capable of generating a value at any XYZ position,
-   creates OpenGL faces for the solids defined.
-
-   init_fn is called at the beginning for initial, and returns an object.
-   free_fn is called at the end.
-
-   compute_fn is called for each XYZ in the specified grid, and returns
-   the double value of that coordinate.  If smoothing is on, then
-   compute_fn will also be called twice more for each emitted vertex,
-   in order to calculate vertex normals (so don't assume it will only
-   be called with values falling on the grid boundaries.)
-
-   Points are inside an object if the are less than `isolevel', and
-   outside otherwise.
-
-   If polygon_count is specified, the number of faces generated will be
-   returned there.
