    // HDRenderPipelineAsset reference the current RenderPipelineSettings use, there is one per supported platform(Currently this feature is not implemented and only one GlobalFrameSettings is available).
    // A Camera with HDAdditionalData have one FrameSettings that configure how it will render.For example a camera use for reflection will disable distortion and postprocess.
    // Additionally on a Camera there is another FrameSettings call ActiveFrameSettings that is created on the fly based on FrameSettings and allow modification for debugging purpose at runtime without being serialized on disk.
    // The ActiveFrameSettings is register in the debug windows at the creation of the camera.
    // A Camera with HDAdditionalData have a RenderPath that define if it use a "Default" FrameSettings, a preset of FrameSettings or a custom one.
    // HDRenderPipelineAsset contain a "Default" FrameSettings that can be reference by any camera with RenderPath.Defaut or when the camera don't have HDAdditionalData like the camera of the Editor.
    // It also contain a DefaultActiveFrameSettings

    // RenderPipelineSettings represent settings that are immutable at runtime.
    // There is a dedicated RenderPipelineSettings for each platform
