Roots, besides the targets themselves, that a subgraph must carry for the
targets to mesh exactly as they do on load: every live IfcProject, each
target's openings and host (with the voiding relationship), the fillings of
those openings (with the filling relationship), and each target's
IfcRelAssociatesMaterial. Relationships the overlay created this session
are included by the same rules. Tombstoned ids are never returned.
