(First, Woohoo! I'm logged on from home!)

Thanks Chris!   Making a demo scene and everything, all I can say is THANKS.

I have a couple of questions which I'll try to find answers to.  Here
though, I'll try to be brief before my session times out and I can't get
logged on again.

One question is, what to do about something like this?  I copied the
View_POV_Include_Stack line from what's in a lot of the POV-Ray distro
#includes.  If fully compliant, the variable needs ScaleConvert_ at the
beginning but to be meaninful it needs to match what's in other #includes:

#ifdef(ScaleConvert_View_POV_Include_Stack)  #debug "including
scaleconvert.incn" #end


#ifdef(View_POV_Include_Stack)  #debug "including scaleconvert.incn" #end

Thanks again,
