/**
 * TItemDataRenderer class
 *
 * TItemDataRenderer is the convient base class for template-based item data renderers.
 * It implements the {@link IItemDataRenderer} interface, and because
 * TItemDataRenderer extends from {@link TTemplateControl}, derived child
 * classes can have templates to define their presentational layout.
 *
 * The following properties are provided by TItemDataRenderer:
 * - {@link getItemIndex ItemIndex}: zero-based index of this renderer in the item list collection.
 * - {@link getItemType ItemType}: item type of this renderer, such as TListItemType::AlternatingItem
 * - {@link getData Data}: data associated with this renderer
