dunno, but it does sound like a possible solution.  obviously it would 
be another way to predefine the pattern before nesting it.

I never really looked into it before because in situations where
I wanted to nest pigments, worse case I would just apply transformations
so as to neutralize one another.  But this time I couldn't solve it in 
that way. I've never heard of "reset_children"
