* add offset to fromArray for consistency with all other fromArray functions in the ThreeJS math library.

* Added matrix3/fixed whitespace

* Fix Matrix3 Matrix4 getInverse throwOnDegenerate

* Update throwOnDegenerate assertion

* move is* properties to prototypes and remove unused ones

* rebuild

* merge dev -> less-is

* remove rebuild from PR

* convert to ES modules

* rebuild

* move shaders back into glsl files

* reinstate polyfills

* add Color.sub()

* add tab

* if result is negative set to 0

* revise doc of color.sub()

This implementation of projectOnVector is faster and shorter than the current version, and it requires no intermediate Vector3 allocation

* Speedup Matrix inverse

* Matrix4 invert speedup

* Remove arguments to allow optimalisations

* Change constructor based on @mrdoob's argument

* Fix issue with renaming of argument

* convert space to tabs

* cleanup docs

* don't forget the linefeed in docs

* docs cleanup

* Update Color.html

* remove usage of parameters in setFromMatrixColumn

* This fixes the usage of setFromMatrixColumn

* tighten up Vector4.

* tighten up Vector3.

* tighten up Vector2.

* add missing "return this" to Ray3.lookAt().

* tighten up Quaternion.

* missing "return this" on Spherical.

* missing "return this" on Euler.  Tighting up code.

* ensure that an empty box is still an empty box aftering being transformed.

* fix docs to match new behavior.

* MatrixN: Deprecated .flattenToArrayOffset.

Instead .toArray consistently allows array and offset to be passed.

* Updated math classes' docs .toArray / .fromArray.

* Automated uniform.<name>.type.

* WebGLRenderer: Added .setTexture deprecation stub.

* Updated ShaderMaterial docs, uniform types.

* Updated Quaternion docs .toArray / .fromArray.

* Updated Quaternion docs, static .slerpFlat.

* Updated math classes' docs, style consistency.

* Updated ShaderMaterial docs, style consistency.

* Implemented user-defined clipping planes.

* Renderer: Minor documentation update.

* Implements object-level clipping.

* Renderer: Minor cosmetic changes.

* Fixed lethal typo in normal shader.

* Let shadows respect .side of object's material.

* Fixed Plane.applyMatrix4.

- Scale denormalized but did not scale the position
- Projection is not supported (solved by documentation)
- Removed unnecessary copying to make up for the normalization
- Still arguably too heavy

* Added custom clipping example.

* Clipping: Fixed transition to disabled state.

* Improved custom clipping example.

- GUI dependency of volume visualization on Enabled state
- Larger radius for cylindrical global clipping area

* No .matrixAutoUpdate = false in clipping example.

* Let ShadowMap check renderer.localClippingEnabled.

* Added a simplified clipping example.

* Triangle: new method .closestPointToPoint

* better initialization of variables

* Matrix4: added preMultiply method

* Matri4: preMultiply -> premultiply

Presumably, the previous version was correct.
