+    \brief Provides a way to apply a 4x4 tranformation matrix to an \l Item
+
+    The Matrix4x4 type provides a way to apply a transformation to an
+    \l 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):
+
+    \qml
+    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)
+        }
+    }
