D3D11DrawContext takes its base context from the deviceContext argument, and the blend state is bound through the base context, which accepts an ID3D11BlendState1 as is. ID3D11DeviceContext1 is optional: RetroArch's threaded video hands v1 cores a deferred-context proxy that answers ID3D11DeviceContext only, and the core now starts on it.
