Well, so far, it's only this single case issue with povray. Using backticks is
normally used for command substitution in the shell itself, not in passing flags
to an application so I think it's working as it should. Putting backticks thus
'res[Low]' is telling the shell itself to process the parameter so it never gets
passed to the povray executable to be parsed by it.

Well, either way it's an interesting problem. As I'm now retired from the IT
life, I have a lot of time for interesting problems ...

Cheers.
