  # This one is, unfortunately, not possible with svg back ends
  #   Cairo lacks a perspective transform (currently), so we have to
  #   use a striping method, which assumes raster. Fortunately, Cairo
  #   has perspective transforms on its roadmap,
  #   so perhaps this can be done someday with all vectors.
