## Detailed Description

The Matrix4x4 type provides a way to apply a transformation to an Item through a 4x4 matrix.

It allows for a combination of rotation, scale, translatation and shearing by using just one tranformation provided in a 4x4-matrix.

The following example rotates a Rectangle 45 degress (PI/4):

      Rectangle {
          width: 100
          height: 100
          color: "red"

          transform: Matrix4x4 {
              property real a: Math.PI / 4
              matrix: Qt.matrix4x4(Math.cos(a), -Math.sin(a), 0, 0,
                                   Math.sin(a),  Math.cos(a), 0, 0,
                                   0,           0,            1, 0,
                                   0,           0,            0, 1)
          }
      }
