Options for performing point attenuation based on geometric error when rendering
point clouds using 3D Tiles.

@param {object} [options] Object with the following properties:
@param {boolean} [options.attenuation=false] Perform point attenuation based on geometric error.
@param {number} [options.geometricErrorScale=1.0] Scale to be applied to each tile's geometric error.
@param {number} [options.maximumAttenuation] Maximum attenuation in pixels. Defaults to the Cesium3DTileset's maximumScreenSpaceError.
@param {number} [options.baseResolution] Average base resolution for the dataset in meters. Substitute for Geometric Error when not available.
@param {boolean} [options.eyeDomeLighting=true] When true, use eye dome lighting when drawing with point attenuation.
@param {number} [options.eyeDomeLightingStrength=1.0] Increasing this value increases contrast on slopes and edges.
@param {number} [options.eyeDomeLightingRadius=1.0] Increase the thickness of contours from eye dome lighting.
@param {boolean} [options.backFaceCulling=false] Determines whether back-facing points are hidden. This option works only if data has normals included.
@param {boolean} [options.normalShading=true] Determines whether a point cloud that contains normals is shaded by the scene's light source.
