-    \class QGraphicsRotation3D
-    \brief The QGraphicsRotation3D class provides rotation in 3 dimensions.
-    \since 4.6
-
-    QGraphicsRotation3D extends QGraphicsRotation with the ability to rotate
-    around a given axis.
-
-    You can provide the desired axis by assigning a QVector3D to the axis
-    property. The angle property, which is provided by QGraphicsRotation, now
-    describes the number of degrees to rotate around this axis.
-
-    By default the axis is (0, 0, 1), giving QGraphicsRotation3D the same
-    default behavior as QGraphicsRotation (i.e., rotation around the Z axis).
-
-    Note: the final rotation is the combined effect of a rotation in
-    3D space followed by a projection back to 2D.  If several rotations
-    are performed in succession, they will not behave as expected unless
-    they were all around the Z axis.

     This can be any axis in 3D space. By default the axis is (0, 0, 1),
-    which is aligned with the Z axis and provides the same behavior
-    for the rotation angle as QGraphicsRotation. If you provide another
-    axis, QGraphicsRotation3D will provide a transformation that rotates

+    QGraphicsRotation will provide a transformation that rotates
     around this axis. For example, if you would like to rotate an item
     around its X axis, you could pass (1, 0, 0) as the axis.
