\class QGraphicsSceneLinearIndex
\brief The QGraphicsSceneLinearIndex class provides an implementation of
a linear indexing algorithm for discovering items in QGraphicsScene.
\since 4.6
\ingroup graphicsview-api
\internal
QGraphicsSceneLinearIndex index is default linear implementation to discover items.
It basically store all items in a list and return them to the scene.
