Orders queries so each comes after every selected query it composes (dependencies first),
keeping the given order among queries that do not depend on each other. Queries in a
composition cycle (stored by an older version that allowed one), and those that depend on
them, come last in their given order; each is listed once, so a cycle is never followed round.
Edges to queries outside the selection are ignored.
