this is continued from [previous](https://calculix.discourse.group/t/cgx-with-new-colormaps/51)discussion, i added rainbow desaturated colormaps since it widely used also. Modified part code extGL.c is placed at [GitHub](https://github.com/xyont/modification/blob/main/extGL_mod2.c), unfortunately i cannot test since have no experiences in compiling and hope someone can tested and works expected. Many thanks

expected colormaps plot result as an example output from OpenRadioss and OpenGeoSys use this type colormaps.
