    \brief Provides utility functions for matrix4x4 when used for 2D transforms.
 
    The \c PlanarTransform is a global object with utility functions.
 
    It is not instantiable; to use it, call the members of the global \c PlanarTransform object
    directly. For example:
 
    \qml
    Item {
        transform: Matrix4x4 { matrix: PlanarTransform.fromAffineMatrix(1, 0, 0.36, 1, -36, 0) }
    }
    \endqml

/*!
    \qmlmethod matrix4x4 PlanarTransform::identity()
 
    Returns a matrix4x4 for the identity transform.
 
    This is equivalent to \l Qt::matrix4x4().

    Returns a matrix4x4 for an affine (non-projecting) 2D transform with the specified values.
 
    This method and its argument order correspond to SVG's \c matrix() function and the
    six-argument QTransform constructor. The result is this 4x4 matrix:
 
    \table
    \row \li \a scaleX \li \a shearX \li 0 \li \a translateX
    \row \li \a shearY \li \a scaleY \li 0 \li \a translateY
