I added some debugging mechanisms that can help create a minimal test case more easily: * In debug mode, you can press `Alt+F10` and the engine will generate a JSON representation of the most recently rendered scene and download it. * Added a script called `generate_scene_test.dart` which can take that JSON and generate a dart file which renders a scene with the identical hierarchy and layout. All the pictures are rendered as squares with random-ish colors.
