/**
 * @class   vtkAnnotatedCubeActor
 * @brief   a 3D cube with face labels
 *
 * vtkAnnotatedCubeActor is a hybrid 3D actor used to represent an anatomical
 * orientation marker in a scene.  The class consists of a 3D unit cube centered
 * on the origin with each face labelled in correspondance to a particular
 * coordinate direction.  For example, with Cartesian directions, the user
 * defined text labels could be: +X, -X, +Y, -Y, +Z, -Z, while for anatomical
 * directions: A, P, L, R, S, I.  Text is automatically centered on each cube
 * face and is not restriceted to single characters. In addition to or in
 * replace of a solid text label representation, the outline edges of the labels
 * can be displayed.  The individual properties of the cube, face labels
 * and text outlines can be manipulated as can their visibility.
 *
 * @warning
 * vtkAnnotatedCubeActor is primarily intended for use with
 * vtkOrientationMarkerWidget. The cube face text is generated by vtkVectorText
 * and therefore the font attributes are restricted.
