/// This sample demonstrates:
///     - Populating a 3D scene with skeletally animated AnimatedModel components;
///     - Moving the animated models and advancing their animation using a custom component
///     - Enabling a cascaded shadow map on a directional light, which allows high-quality shadows
///       over a large area (typically used in outdoor scenes for shadows cast by sunlight)
///     - Displaying renderer debug geometry
