++ // Item2DPass test scene.
++ // A Qt Quick 2D Rectangle (red) is embedded inside a 3D Node.
++ // A SubRenderPass with passMode: RenderPass.Item2DPass renders the 2D item
++ // into the 3D scene. The test verifies that red pixels appear (the 2D item
++ // rendered), and that changing the item colour at runtime changes the output.
