    * It's layer to simulate Globe atmosphere.
    * There's 2 modes : simple and realistic (atmospheric-scattering).
     *
    * The atmospheric-scattering it is taken from :
    * * [Atmosphere Shader From Space (Atmospheric scattering)](http://stainlessbeer.weebly.com/planets-9-atmospheric-scattering.html)
    * * [Accurate Atmospheric Scattering (NVIDIA GPU Gems 2)](https://developer.nvidia.com/gpugems/gpugems2/part-ii-shading-lighting-and-shadows/chapter-16-accurate-atmospheric-scattering).
    *
    * @param {string} id - The id of the layer Atmosphere.
    * @param {Object} [options] - options layer.
    * @param {number} [options.Kr] - `Kr` is the rayleigh scattering constant.
    * @param {number} [options.Km] - `Km` is the Mie scattering constant.
    * @param {number} [options.ESun] - `ESun` is the brightness of the sun.
    * @param {number} [options.g] - constant `g` that affects the symmetry of the scattering.
    * @param {number} [options.innerRadius] - The inner (planetary) radius
    * @param {number} [options.outerRadius] - The outer (Atmosphere) radius
    * @param {number[]} [options.wavelength] - The constant is the `wavelength` (or color) of light.
    * @param {number} [options.scaleDepth] - The `scale depth` (i.e. the altitude at which the atmosphere's average density is found).
    * @param {number} [options.mieScaleDepth] - not used.
