Trait CompositionSurfaceVisualHooks 

pub trait CompositionSurfaceVisualHooks: CompositionContainerVisualHooks {
    // Provided methods
    fn initialize_defaults_extra(&self) { ... }
    fn validate_surface_change(
        &self,
        _old_value: &Option<Rc<dyn ICompositionObject>>,
        _new_value: &Option<Rc<dyn ICompositionObject>>,
    ) { ... }
    fn on_surface_changed(&self) { ... }
    fn on_surface_changing(&self) { ... }
}

The partial methods of CompositionSurfaceVisual: implemented by the class that embeds CompositionSurfaceVisualProps. Every hook defaults to doing nothing.
