Fix Inconsistent type on `kernelRadius` to a number. 
The plain version of the SSAOPass.js takes a number type
but it's typed as a `boolean` here.

Do not require a camera for DeviceOrientationControls

Change "Camera" to "Object3D"

Based on a quick look at the source code of DeviceOrientationControls.js, a camera is not needed for the controls to work, since the controls do not use any methods or properties that are only available on cameras.

Case in point: for the [jsdoom](https://github.com/pineapplemachine/jsdoom) 3D view, I am using the DeviceOrientationControls to change the orientation of a "view head" object, which has some cameras as its children.

TS: Remove 4 redundant definitions inherited from Curve

OrbitControls: Add comments to calls of preventDefault().

Docs: Recommend Servez

Editor: Add option for shadow type configuration.

Fix gimbal lock misconception in quaternion doc

WebGLRenderer: Ignore map alpha in opaque materials

Fix glTF mask

KeyframeTrack: Clarify if-clause in .trim().

Examples: Add CSM implementation

Vector2.angle() performance

ObjectLoader: Remove usage of LegacyJSONLoader.

Editor: Add support for vertexTangents.

CatmullRomCurve3.getPoint() should accept an [optional Vector3 target](https://github.com/mrdoob/three.js/blob/master/src/extras/curves/CatmullRomCurve3.js#L104) argument. It's missing in the TypeScript declaration file, which leads to compiler errors if users try to use this option.

WebGLRenderLists: Avoid possible memory leak when managing render items.

Clean up tests on BufferGeometryUtils and GLTFExporter.

Material: Move vertexTangents to MeshStandardMaterial.

BokehShader: Fix wrong format of render target.
