Major architecture upgrade: - Add native render pass merging (hardware pass grouping, load/store op inference) - Implement heap-based aliasing for textures & buffers (D3D12-style) - Unify resource model: buffers and textures in one registry - Extend builder API for buffer creation/usage, access flags, hints - Improve barrier/state tracking (buffer hints, indirect argument state) - Update caching, hashing, and debug output for new model - Add enums/structs: AttachmentLoadOp, StoreOp, BufferHint, etc. - D3D12 backend: support named resources, temp upload buffers, correct heap usage - Update docs, benchmarks, and project files for new features Brings render graph closer to AAA engine standards, enabling efficient memory usage, lower driver overhead, and a more flexible API.
