     * The SPS is a single updatable mesh. The solid particles are simply separate parts or faces fo this big mesh.
     *As it is just a mesh, the SPS has all the same properties than any other BJS mesh : not more, not less. It can be scaled, rotated, translated, enlighted, textured, moved, etc.

     * The SPS is also a particle system. It provides some methods to manage the particles.
     * However it is behavior agnostic. This means it has no emitter, no particle physics, no particle recycler. You have to implement your own behavior.

         * * The parameter `closeArray` (boolean, default false) creates a seam between the first and the last paths of the path array

         * * Note that if you use the parameters `uvs` or `colors`, the passed arrays must be populated with the right number of elements, it is to say the number of ribbon vertices. Remember that if you set `closePath` to `true`, there's one extra vertex per path in the geometry

         * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.

         * * Each array (color or UVs) is always ordered the same way : the first element is the bottom cap, the last element is the top cap. The other elements are each a ring surface.
         * * If `enclose` is false, a ring surface is one element.
         * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.

         * Creates a polyhedron mesh
         * * The parameter `type` (positive integer, max 14, default 0) sets the polyhedron type to build among the 15 embbeded types. Please refer to the type sheet in the tutorial to choose the wanted type
         * * The parameter `size` (positive float, default 1) sets the polygon size
         * * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value)
         * * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overwrittes the parameter `type`
         * * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron
         * * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`)
         * * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : http://doc.babylonjs.com/tutorials/CreateBox_Per_Face_Textures_And_Colors
         * * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored
         * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4). Detail here : http://doc.babylonjs.com/babylon101/discover_basic_elements#side-orientation
         * * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created
         * @param name defines the name of the mesh
         * @param options defines the options used to create the mesh
         * @param scene defines the hosting scene

     * Draco compression (https://google.github.io/draco/)
     *
     * This class wraps the Draco module.
     *
     * **Encoder**
     *
     * The encoder is not currently implemented.
     *
     * **Decoder**
     *
     * By default, the configuration points to a copy of the Draco decoder files for glTF from the babylon.js preview cdn https://preview.babylonjs.com/draco_wasm_wrapper_gltf.js.
     *
     * To update the configuration, use the following code:
     * ```javascript
     *     BABYLON.DracoCompression.Configuration = {
     *         decoder: {
     *             wasmUrl: "<url to the WebAssembly library>",
     *             wasmBinaryUrl: "<url to the WebAssembly binary>",
     *             fallbackUrl: "<url to the fallback JavaScript library>",
     *         }
     *     };
     * ```
     *
     * Draco has two versions, one for WebAssembly and one for JavaScript. The decoder configuration can be set to only support Webssembly or only support the JavaScript version.
     * Decoding will automatically fallback to the JavaScript version if WebAssembly version is not configured or if WebAssembly is not supported by the browser.
     * Use `BABYLON.DracoCompression.DecoderAvailable` to determine if the decoder is available for the current session.
     *
     * To decode Draco compressed data, create a DracoCompression object and call decodeMeshAsync:
     * ```javascript
     *     var dracoCompression = new BABYLON.DracoCompression();
     *     var vertexData = await dracoCompression.decodeMeshAsync(data, {
     *         [BABYLON.VertexBuffer.PositionKind]: 0
     *     });
     * ```
