/// The Init method precomputes the atmosphere textures. It first allocates the
/// temporary resources it needs, then calls Precompute to do the
/// actual precomputations, and finally destroys the temporary resources.
///
/// Note that there are two precomputation modes here, depending on whether we
/// want to store precomputed irradiance or illuminance values:
///
/// In precomputed irradiance mode, we simply need to call
/// Precompute with the 3 wavelengths for which we want to precompute
/// irradiance, namely kLambdaR, kLambdaG, kLambdaB(with the identity matrix for
/// luminance_from_radiance, since we don't want any conversion from radiance to luminance).
///
/// In precomputed illuminance mode, we need to precompute irradiance for
/// num_precomputed_wavelengths, and then integrate the results,
/// multiplied with the 3 CIE xyz color matching functions and the XYZ to sRGB
/// matrix to get sRGB illuminance values.
/// A naive solution would be to allocate temporary textures for the
/// intermediate irradiance results, then perform the integration from irradiance
/// to illuminance and store the result in the final precomputed texture. In
/// pseudo-code (and assuming one wavelength per texture instead of 3):
///
/// create n temporary irradiance textures
/// for each wavelength lambda in the n wavelengths:
/// precompute irradiance at lambda into one of the temporary textures
/// initializes the final illuminance texture with zeros
/// for each wavelength lambda in the n wavelengths:
/// accumulate in the final illuminance texture the product of the
/// precomputed irradiance at lambda (read from the temporary textures)
/// with the value of the 3 sRGB color matching functions at lambda
/// (i.e. the product of the XYZ to sRGB matrix with the CIE xyz color matching functions).
///
/// However, this be would waste GPU memory. Instead, we can avoid allocating
/// temporary irradiance textures, by merging the two above loops:
///
/// for each wavelength lambda in the n wavelengths:
/// accumulate in the final illuminance texture (or, for the first
/// iteration, set this texture to) the product of the precomputed
/// irradiance at lambda (computed on the fly) with the value of the 3
/// sRGB color matching functions at lambda.
