AnimNodeResources do not reference an actual node anymore. However, we still need descriptors to check whether connections are valid.
For this we have VirtualNodeDescriptors for which all sockets point to nullptr.
- Refactored NodeSocketAccessor to NodeDescriptor.
- Connections are wired up during AnimGraph instantiation.
- Output and input sockets point to the same memory location.
- No re-wiring needed during evaluation.
- AnimGraph are pre-allocated (refactoring for less memory usage postponed).
- Evaluation of AnimGraph now possible from the editor.
Instead of wiring up pointers with prepareNodeEval() and finishNodeEval() use for each connection a single memory block where outputs and inputs point to.
- Animation Data are always referenced via a pointer in nodes.
- Animation Data storage pointers are injected from graph when node is evaluated.
- Node value outputs always stored in node.
- Node value inputs always referenced via pointer. References are created when instantiating the graph.
