- D3D12Shader now implements IShader interface with GetBytecode, GetBytecodeSize, GetType, GetInputLayout - D3D12SwapChain now implements ISwapChain interface with GetBackBuffer returning IResource* - Added D3D12Texture back buffer storage to SwapChain - Fixed ISwapChain const correctness (GetCurrentBackBufferIndex, GetBackBuffer) - main.cpp: use GetD3D12Bytecode() instead of GetBytecode() for PSO creation
