 For a simple global-scope "resource" parameter (e.g., HLSL `Texture2D t : register(t3)`) the `category` tells what kind of resource the parameter consumes (e.g., `slang::ParameterCategory::ShaderResource`), the `index` gives the register number (`3`), and `space` gives the register "space" (`0`) as added for D3D12.
