  # Restore the new_content_stream method from PDF::Core::Page
  #
  # The prawn-templates gem relies on the new_content_stream method on
  # PDF::Core::Page, which was removed in pdf-core 0.3.1. prawn-templates is
  # used for importing a single-page PDF into the current document.
  #
  # see https://github.com/prawnpdf/pdf-core/commit/67f9a08a03bcfcc5a24cf76b135c218d3d3ab05d
