 are also shared, and once a shared node is live, the
 capabilities cannot be changed.  To assign capabilities to
 Primitives with the same parameters, either set the
 capabilities before the primitive is set live, or specify the
 Primitive.GEOMETRY_NOT_SHARED constructor parameter when
 creating the primitive.
