// Function: PandaNode::set_unexpected_change
// Access: Published
// Description: Sets one or more of the PandaNode::UnexpectedChange
// bits on, indicating that the corresponding property
// should not change again on this node. Once one of
// these bits has been set, if the property changes, an
// assertion failure will be raised, which is designed
// to assist the developer in identifying the
// troublesome code that modified the property
// unexpectedly.
//
// The input parameter is the union of bits that are to
// be set. To clear these bits later, use
// clear_unexpected_change().
//
// Since this is a developer debugging tool only, this
// function does nothing in a production (NDEBUG) build.
