Those nodes in a scene that are creating references in the view get a
unique ID that is counted up from 1. The IDs can be managed by the
scene or browser and IDs should be recycled if a node is deleted, so
that the IDs are usually dense and can be used as direct array index.
What the array contains depends on the view, I would say. A GL view
might store GL list indices. A different view might store something
else. How do you like this concept?

Best regards,
