++ // RenderOutputProvider.ScreenTexture test.
++ // A red sphere is rendered by the standard internal rendering pipeline.
++ // A user pass uses RenderOutputProvider.ScreenTexture to read the rendered scene
++ // texture and displays it via SimpleQuadRenderer, covering the full view.
++ // The C++ test verifies that:
++ // (1) The ScreenTexture contains the rendered scene (red pixels from the sphere).
++ // (2) Changing the sphere colour to blue causes the ScreenTexture output to change.
