Yep, I see that now.

It already contains the nReduced parameter, which I am using for this 
purpose. The only problem is that it doesn't allow for different settings 
for cube and chequer, and thus cannot be set differently for the two. That 
should be fixed by the above. No reason to introduce new parameters, as far 
as I can see.
