Detailed Description

This mixin can be used for unique datas on anim graph nodes that manually need to increase pose and data ref counts for nodes a hierarchy level up or neighbor nodes with a risk of the node not being output. An example would be the state machine where the active nodes can change within the update method due to ending or newly started transitions. We need some way to keep track of the nodes that increased the data and pose ref counts at a level up in the hierarchy.
