Does the window automatically repaint whenever the scene has changed?

	// C# example
	// Simple script that lets you render the main camera in an editor Window.
	
	using UnityEngine;
	using UnityEditor;
	
	public class CameraViewer : EditorWindow {
		Camera camera = Camera.main;
		RenderTexture renderTexture;
	
		[MenuItem("Example/Camera viewer")]
		static void Init() {
			EditorWindow editorWindow = GetWindow(typeof(CameraViewer));
			editorWindow.autoRepaintOnSceneChange = true;
			editorWindow.Show();
		}
		public void Awake () {
			renderTexture = new RenderTexture((int)position.width, 
						(int)position.height, 
						(int)RenderTextureFormat.ARGB32 );
		}
		public void Update() {
			if(camera != null) {
				camera.targetTexture = renderTexture;
				camera.Render();
				camera.targetTexture = null;	
			}
			if(renderTexture.width != position.width || 
				renderTexture.height != position.height)
				renderTexture = new RenderTexture((int)position.width, 
								(int)position.height, 
								(int)RenderTextureFormat.ARGB32 );
		}
		void OnGUI() {
			GUI.DrawTexture( new Rect( 0.0f, 0.0f, position.width, position.height), renderTexture );	
		}
