  * @param[in] lambda_identity Regularisation parameter of the PCA shape fitting.
  * @param[in] num_expression_coefficients_to_fit How many shape-coefficients to fit (all others will stay 0). Should be bigger than zero, or std::nullopt to fit all coefficients. Only used for expression-PCA fitting.
  * @param[in] lambda_expressions Regularisation parameter of the expression fitting. Only used for expression-PCA fitting.
  - * @param[in] initial_rendering_params Currently ignored (not used).
  * @param[in,out] pca_shape_coefficients If given, will be used as initial PCA shape coefficients to start the fitting. Will contain the final estimated coefficients.
  * @param[in,out] expression_coefficients If given, will be used as initial expression blendshape coefficients to start the fitting. Will contain the final estimated coefficients.
  * @param[out] fitted_image_points Debug parameter: Returns all the 2D points that have been used for the fitting.
