* Added TTFLoader and opentype.min.js

* Updated TTFLoader to work with last version of opentype and added example

* Removed batch for py http server

Eval was being used to construct a regex pattern. This replaces that with the RegExp constructor.

* Initial GLTFLoader updates so it will also obtain async resources over the network

* First take at adding shader support to new GLTFLoader

* First working custom shaders version of GLTFLoader.js

* Fully working custom GLTF shaders + general library fix-ups

* Add skins, animations, lights, extensions and continue to refactor the library

* Refactor new GLTFLoader (seperate glTF parsing and internal library building)

* Fix GLSL shader update binding to point at the correct nodes + more general refactoring

* Make _each thenable and refactor dependencies graph + other minor fixes

* Improves spec compliance: primitive.mode is optional

* Update GLTFLoader v2 with feedback on PR: https://github.com/mrdoob/three.js/pull/9786

- Replace .set(...) with .fromArray(...) where possible for THREE.js Math objects (thanks @mrdoob)
- Include fix for https://github.com/mrdoob/three.js/issues/8381 (thanks @cx20)
- Move THREE.GLTFShaders to THREE.GLTFLoader.Shaders
- Move THREE.GLTFAnimator to THREE.GLTFLoader.Animations
- Rename .setBaseUrl(...) to .setPath(...)
- Update demo page 'examples/webgl_loader_gltf_new.html' with renamed APIs

* Replace 'examples/webgl_loader_gltf.html' with new version of GLTFLoader

* Update documentation at /docs/?q=gltf#Reference/Loaders/GLTFLoader to reference new GLTFLoader

* Move /examples/js/loaders/gltf/* to /examples/js/loaders/deprecated/gltf/*

* Actually add a fix for https://github.com/mrdoob/three.js/issues/8381

* Re-fix https://github.com/mrdoob/three.js/issues/8381 in a more logical way

* Update material parameter checking and validation.

* Fix issue whereby the spec says doubleSided and transparent should be in the 'values' section but every use of these params I've seen in the wild has been outside this section

* Ambient is not a valid properties for THREE.js materials

* THREE textures have flipY set to true by default. By setting to false we can remove double flip from GLTFLoader

* Fix issue where Firefox Promise then callback can not correctly keep track of its key

* Remove debugging from examples/loaders/deprecated/gltf/glTFLoader.js

* Refactor waitForDependencies in to _withDependencies. Remove need for global library.* tracking. Other general refactoring

Fix Safari glTF rendering issue re: WebGLRenderingContext constant values are not exposed (see: https://github.com/mrdoob/three.js/issues/8973) (#9721)

This targets separate but logically joined lines (separated by a continuation character, e.g. `\`) and joins them.

OBJLoader: Fix bug that produced geom group and multi-material for objects where the last line is a material change. (#9645)

This was incorrectly used for multi-material even if no faces for the new material were declared.

Fixes #9495

`String.prototype.replace` only targets and replaces the first occurrence of a string. By using a regex with the global flag, all instances of a pattern are replaced.

* Optimize Outline rendering of MMD

* Use Layers instead of visible for MMDHelper.renderOutline() optimization

* DRYer texture creation for different map types

Noticed there was a fair bit of repetition in each map line case. This pulls the case logic out into a reusable function

This also adds support for texture parameters for specular maps as a result. (Expands on #9311 and #9308)

* Change style of function declaration

* MTLLoader: Support for texture parameters

 -s u v w for scale (w is ignored)
 -o u v w for offset (w is ignored)
 -bm s for bumpmap scale

* Fix positional argument to get bumpmap scale

* Trim texture url to prevent trailing spaces

* Fix calls to getTextureParams (pass material parameters)

* Add missing 'var's

* MTL Loader support for map_Ks

* removed amature console log

`value[ 1 ] === 0` is repeated. Looks like it should be `value [ 2 ] === 0` the second time.

* Adds a BVH Loader & example #5524

* bVHLoader example fixed empty mesh errors.

* BVHLoader: replaced internal quaternions with THREE.Quaternion

* added BVHLoader example to example files

* removed arrow function notation

* BVHLoader example: replaced example animation.

ShaderChunk: Moved normal_flip out of envmap_fragment and normal_fragment. See fc1159a6.
