-----------

instancesWithClassName(), dominatedNodes(), retainedNodes(), and
retainers() each collected raw node/edge indices into an array and
then called .map(this.serializeNode/serializeEdge) to produce the
result, allocating and traversing a throwaway array for no reason.
Push the serialized node/edge directly in the collection loop instead.
