Merge is internally represented as a complex CSG. It takes more memory
and generally takes longer to render than the equivalent union. This
is not true in some special cases but this shouldn't be one of them.

Wrong (I think). It just represents it as a complex CSG to remove the
inner surfaces.

If the spheres were transparent and stacked, maybe. I doubt it will
help in the stones macro case.
