-
-     The QTransform provided through this member does include information about
-     any perspective transformations applied to the view or item. To get the
-     correct transformation matrix, use QPainter::transform() on the painter
-     passed into the QGraphicsItem::paint() implementation.
-
-     This matrix is the combination of the item's scene matrix and the matrix
-     of the painter used for drawing the item. It is provided for convenience,
-     allowing anvanced level-of-detail metrics that can be used to speed up
-     item drawing.
-
-     To find the dimensions of an item in screen coordinates (i.e., pixels),
-     you can use the mapping functions of QTransform, such as QTransform::map().
-
-     This member is only initialized for items that have the
-     QGraphicsItem::ItemUsesExtendedStyleOption flag set.
