Ah, now I see. Yes, being able to do either as needed would be better
than one or the other.

Well, I'll comment that I think this could be a more logical general
syntax. If "pattern" could be used anywhere a function { pigment {...} }
is now used, so it is consistant in its usage (or even if were more 
like "function { pattern { ... } }" ) Calling it a pigment function 
implies it affects the pigmentation somehow, when in fact it was
just meant to imply it uses the texture patterns, so changing 
the syntax to use "pattern" in place of "pigment" would be more
self explanatory.
