docs: Sanitizes the name of a file (for including graphics in LaTeX).
  
      :param name: the name of the file to sanitize.
      :type name: str
  
      :returns: the sanitized name.
  
      For example, if the name of the graphic file is ``test.1.png``, the
      sanitized version of it for LaTeX is ``{test.1}.png``.
