#' Wavelength to RGB
#'
#' This function converts a given wavelength of light to an 
#' approximate RGB color value. 
#'
#' @param wavelength A wavelength value, in nanometers, in the human visual range from 380 nm through 750 nm.
#'        These correspond to frequencies in the range from 789 THz through 400 THz.
#' @param gamma The \eqn{\gamma} correction for a given display device. The linear RGB values will require
#'        gamma correction if the display device has nonlinear response.
#' @return a color string, corresponding to the result of \code{\link[grDevices]{rgb}} on the

// Creating a node graph editor for Dear ImGui
// Quick sample, not production code! 
// This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff,
// which ended up feeding a thread full of better experiments.
// See https://github.com/ocornut/imgui/issues/306 for details

// Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors
