      """
      Bronstein's full partial fraction decomposition algorithm.
  
      Given a univariate rational function ``f``, performing only GCD
      operations over the algebraic closure of the initial ground domain
      of definition, compute full partial fraction decomposition with
      fractions having linear denominators.
  
      Note that no factorization of the initial denominator of ``f`` is
      performed. The final decomposition is formed in terms of a sum of
      :class:`RootSum` instances.
