The idea is to add anThis patch adds an integer identifier to nodes that does non't change when
the node name changes. This identifier can be used by different systems
to reference a node. This may be important to store caches and simulation
states per node, because otherwise those would always be invalidated
when a node name changes.
Additionally, this kind of identifier could make some things more efficient,
because with it an integer is enough to identify a node and one does not
have to store the node name.
Not entirely sure if this is a good idea yet, I'm just checking how difficultTODO:
the implementation would be.- Figure out how to get the node name from the viewer path, or use node names for the viewer path (revert that part of the change)
