6 ## Enable debug rendering
8 Setting DALI_DEBUG_RENDERING environment variable will enable the visual debuging.
10 Then, every concrete visual ( ColorVisual, BorderVisual, ImageVisual, GradientVisual, etc. ) is replaced with a DebugVisual object.
11 Debug visual renders a simple quad wireframe, so that the control layout and scene structure is clearly displayed.
