This inline function is just a convenient way to call TypeRegistry::register_type(),...
This template class is a special kind of AnimChannel that always returns just one fixed value.
TypeHandle is the identifier used to differentiate C++ class types.
virtual bool has_changed(int last_frame, double last_frac, int this_frame, double this_frac)
Returns true if the value has changed since the last call to has_changed().
