dealing with hierarchy:

you can render in passes. first pass traverses the sg and renders all
opaque objects, keeping an ordered list of opaque objects with their
transforms. second pass renders the opaque list. that's how they do it
in maveric.

in perfomer it is even more flexible - you define the "traversal pass"
which simply collects objects in several "bins" (e.g. opaque bin,
transparent bin, whatever else bin) and how each bin is ordered (or
not at all, but usually they order opaque by graphics state) and in
which order bins are rendered.
