do not have "sibling" subfaces (with identical state) overlap each other. their
relative ordering is not guaranteed by the flt loader. it optimizes super/sub
face trees by processing them in breadth first order (not depth first). this
allows subfaces to be gathered into the fewest possible geosets while providing
the correct draw order in most use cases.
