Trait CompositionVisualCollectionHooks 

pub trait CompositionVisualCollectionHooks<TItem: ICompositionObject + ?Sized>: ICompositionObjectHost {
    // Provided methods
    fn initialize_defaults_extra(&self) { ... }
    fn on_before_added(&self, _item: &Rc<TItem>) { ... }

    fn on_clear(&self) { ... }
}

The partial methods of CompositionVisualCollection: implemented by the class that embeds CompositionVisualCollectionProps. TItem is the UI-thread class of the items (CompositionVisual). Every hook defaults to doing nothing.
