message: gltfpack: Rename extension to KHR_mesh_quantization
diff: // files can be further compressed with deflate/etc.
  //
  // To load regular glb files, it should be sufficient to use a standard glTF loader (although note that these files
  -// use quantized position/texture coordinates that are technically invalid per spec; THREE.js and BabylonJS support
  -// these files out of the box).
  +// use quantized position/texture coordinates that require support for KHR_mesh_quantization; THREE.js and BabylonJS
  +// support these files out of the box).
  // To load packed glb files, meshoptimizer vertex decoder needs to be integrated into the loader; demo/GLTFLoader.js
  // contains a work-in-progress loader - please note that the extension specification isn't ready yet so the format
  // will change!
