Now, with POV-Ray development started in earness again, the use of the 
'optional' parameter may become interesting again. I have to delve into 
its use because I do not entirely understand /how/ it works, but with a 
couple of test scenes I shall get the hang of it I expect.

Slow work somehow, but it is growing. I hope it will meet your 
expectations ;-)

That "Granite Editor" of yours, Can you post me a copy? It looks like an 
interesting tool to use in the approach to re-defining the color_maps, 
and I do it intuitively by hand now. Thanks.
