// Notes:
//
// If no animation is used (i.e. the value of "clock" is zero) the system will
// switch to rgb preview mode without spectral rendering.
// 
// But if in this case "SpectralWavelength" is declared before this file is
// included, the *one* file for the specified wavelength will be rendered.
