+ * A loader for the Draco format.
+ *
+ * [Draco](https://google.github.io/draco/) is an open source library for compressing
+ * and decompressing 3D meshes and point clouds. Compressed geometry can be significantly smaller,
+ * at the cost of additional decoding time on the client device.
+ *
+ * Standalone Draco files have a `.drc` extension, and contain vertex positions, normals, colors,
+ * and other attributes. Draco files do not contain materials, textures, animation, or node hierarchies –
+ * to use these features, embed Draco geometry inside of a glTF file. A normal glTF file can be converted
+ * to a Draco-compressed glTF file using [glTF-Pipeline](https://github.com/CesiumGS/gltf-pipeline).
+ * When using Draco with glTF, an instance of `DRACOLoader` will be used internally by {@link GLTFLoader}.
+ *
+ * It is recommended to create one DRACOLoader instance and reuse it to avoid loading and creating
+ * multiple decoder instances.
+ *
+ * `DRACOLoader` will automatically use either the JS or the WASM decoding library, based on
+ * browser capabilities.
+ *
+ * ```js
+ * const loader = new DRACOLoader();
+ * loader.setDecoderPath( '/examples/jsm/libs/draco/' );

+ * A loader for the STL format, as created by Solidworks and other CAD programs.
+ *
+ * Supports both binary and ASCII encoded files. The loader returns a non-indexed buffer geometry.
+ *
+ * Limitations:
+ * - Binary decoding supports "Magics" color format (http://en.wikipedia.org/wiki/STL_(file_format)#Color_in_binary_STL).
+ * - There is perhaps some question as to how valid it is to always assume little-endian-ness.
+ * - ASCII decoding assumes file is UTF-8.
+ *
+ * ```js
+ * const loader = new STLLoader();
+ * const geometry = await loader.loadAsync( './models/stl/slotted_disk.stl' )
+ * scene.add( new THREE.Mesh( geometry ) );
+ * ```
+ * For binary STLs geometry might contain colors for vertices. To use it:
+ * ```js
+ * // use the same code to load STL as above
+ * if ( geometry.hasColors ) {
+ * 	material = new THREE.MeshPhongMaterial( { opacity: geometry.alpha, vertexColors: true } );
+ * }
+ * const mesh = new THREE.Mesh( geometry, material );
+ * ```
+ * For ASCII STLs containing multiple solids, each solid is assigned to a different group.
+ * Groups can be used to assign a different color by defining an array of materials with the same length of
+ * geometry.groups and passing it to the Mesh constructor:
+ *
+ * ```js
+ * const materials = [];
+ * const nGeometryGroups = geometry.groups.length;
+ *
+ * for ( let i = 0; i < nGeometryGroups; i ++ ) {
+ * 	const material = new THREE.MeshPhongMaterial( { color: colorMap[ i ], wireframe: false } );
+ * 	materials.push( material );
+ * }
