// The SbPimplPtr<> class is loosely based on the boost::pimpl_ptr<>-
// proposal of 2005 by Asger Mangaard.
//
// It is reimplemented here as separate classes, not with policy-based
// templates, because we still try to support compilers that don't support
// template templates (e.g. Visual C++ 6).
//
// See also SbLazyPimplPtr<>, our implementation of the lazy-creation policy.
