  // StartRegistration is an old API from before
  // ImageRegistrationMethod was a subclass of ProcessObject.
  // Historically, one could call StartRegistration() instead of
  // calling Update().  However, when called directly by the user, the
  // inputs to ImageRegistrationMethod may not be up to date.  This
  // may cause an unexpected behavior.
  //
  // Since we cannot eliminate StartRegistration for backward
  // compatibility reasons, we check whether StartRegistration was
  // called directly or whether Update() (which in turn called
  // StartRegistration()).
