x,y changed to x,y,z, and width,height changed to width,height and depth.

* CurvePath.getPoints() for Arcs resolution should be doubled

- like previous behaviour
- see #9079

* CurvePath: increase resolution of spline curves

* Fix for background clipping when using logarithmicDepthBuffer feature

* Changed subdivisions from 5 to 4

* Whitespace fix

Added the missing core/Layers.js, and removed core/Face4.js, from the canvas.json build include. The canvas only version of three.js now builds properly using the build scripts. (#9251)

# Conflicts:
#	editor/js/libs/app.js

* build.js ux improvements

- script can be run from any directory, uses script dir to determine
  relative paths to other needed files
- by default, determine minified file name from `output` file name (e.g.
  three.js -> three.min.js). minified file name can be explicitly set
  directly via a new option `minifiedoutput`
- if `minify` is true, still build un-minified file
- ensure sourcemap url refers to actual minified file name, (before,
  three.min.js was hard-coded)

* updating npm scripts with new build script usage

* fix set automatic .transparent NodeMaterial

* minimalist optimization

* Update index.html

* Revert "Update index.html"

This reverts commit 76f47860891b9bc87b0243ec79378d325a725650.

* added options for gammaInput and gammaOutput

* added storage for gammaInput and gammaOutput

* added gammaInOut values to json export

* further adds

added gammaInOutput options to the app and fixed them not loading on
page reload

* dang that was wrong

JPEGs can't have an alpha channel, so it's optimal to load them as RGB
textures instead of RGBA. This saves 25% of texture memory on
OpenGL-based WebGL implementations. The optimization is especially
significant on memory-constrained mobile platforms.

* fix(blender-exporter): Animation._parse_pose_action now returns only existing keyframes,  Animation._find_channels returns all channels
fix(animation): AnimationClip uses id instead index

* fix(blender-exporter): Animation._parse_pose_action scale order
