◆ findItems()

QList< QGraphicsItem * > QGraphicsViewPrivate::findItems ( const QRegion &  exposedRegion,
bool *  allItems,
const QTransform &  viewTransform 
) const

Adjustments in findItems: mapToScene(QRect) forces us to adjust the

input rectangle by (0, 0, 1, 1), because it uses QRect::bottomRight() (etc) when mapping the rectangle to a polygon (which is wrong). In addition, as QGraphicsItem::boundingRect() is defined in logical space, but the default pen for QPainter is cosmetic with a width of 0, QPainter is at risk of painting 1 pixel outside the bounding rect. Therefore we must search for items with an adjustment of (-1, -1, 1, 1).
