This function is only intended to be used when implementing new canvas items, typically container items such as CanvasGroup.
It creates a new canvas item for the given item model, and recursively creates items for any children.
It uses the create_item virtual method if it has been set. Subclasses of Canvas
can define this method if they want to use custom views for items.
It emits the item_created signal after creating the view, so application code can connect signal handlers to the new view if desired.
