+\section2 Property types
+
+Support for various math and geometry-related value types, including QVector2D, QVector3D, QVector4D,
+QMatrix4x4 and QQuaternion, as well as QColor and QFont, are now provided by QtQuick.  Properties of
+these types can be declared in QML documents via the property syntax where the type name is \c vector2d,
+\c vector3d, \c vector4d, \c matrix4x4, \c quaternion, \c color and \c font respectively.
+
+QtQuick also provides implementation for the various value type factory or utility functions of the
+\c Qt object which return or operate on values of the above types.  The functions are:
+\table

+  \row

+  \li Qt.rgba(), Qt.hsla(), Qt.tint(), Qt.lighter(), Qt.darker(), Qt.colorEqual()

+The \c Qt.rgba(), \c Qt.hsla(), \c Qt.tint(), \c Qt.lighter(), \c Qt.darker()
+and \c Qt.fontFamilies() functions already existed in \c QtDeclarative prior
+to QtQuick 2.0; the other functions are all new in QtQuick 2.0.
