Updates child graphics items to represent current state and content.
\note It is a good habit to reuse child items as much as possible as this improves
performance, especially when item recycling is used.
Most of the HbAbstractViewItem derived classes inside Hb library are optimised for performance.
Layout files are loaded only if child items are created or deleted. Loading layout
files is triggered by calling HbWidget::repolish().
Classes deriving from HbAbstractViewItem outside Hb, should either always call explicitly
repolish() or if they are also optimised for performance only when child items are created or deleted
in the custom view item.
Here is an example of custom view item that reuses its child items. The custom view item does not
create or delete child items.
