- Remove void* parameters from RHICommandList abstract interface
- TransitionBarrier, SetVertexBuffer, SetIndexBuffer, SetRenderTargets,
ClearRenderTarget, ClearDepthStencil, CopyResource now use RHIResourceView*
- SetPipelineState now uses RHIPipelineState* instead of void*
- Simplified SetVertexBuffer to 3 params, SetIndexBuffer to 2 params
- Add internal D3D12 APIs for native type support (low-level escape hatch)
- Fix OpenGL SetRenderTargets to call glDrawBuffers for MRT support
- Update tests to match new interface signatures
All 289 RHI tests pass (158 unit + 64 OpenGL backend + 58 D3D12 backend + 8 integration + 1 disabled)
- Add m_boundRenderTargets and m_boundDepthStencil members to D3D12CommandList
- SetRenderTargetsHandle now saves bound RTV handles for later clear operations
- ClearRenderTargetView(ID3D12Resource*, ...) clears all bound render targets
- Reset() clears bound targets list
- Follows D3D12 best practice: RTV is bound via OMSetRenderTargets, then cleared
- Add default value handling for sampleCount, mipLevels, depth in CreateTexture
- Add RTV descriptor heap to D3D12CommandList for future ClearRenderTarget implementation
- ClearRenderTarget remains stub (requires full D3D12 render pipeline state)
- Add DepthStencilState and BlendState structs to RHICommandList
- Add SetPrimitiveTopology, SetDepthStencilState, SetStencilRef,
SetBlendState, SetBlendFactor virtual methods
- Implement new methods in OpenGL backend with full state control
- Implement stub methods in D3D12 backend (states controlled via PSO)
