This class keeps track of all the state we must make note of during the graph traversal,...
void compose(const DeferredNodeProperty &other)
Composes this state with the next one encountered on a lower node during the apply traversal.
void apply_to_node(PandaNode *node)
Applies whatever state is appropriate to the node.
A basic node of the scene graph or data graph.
