  # - TODO: spec says that we should make PNG file on the output.
  #   But currently we recognize output file type by extension,
  #   and nautilus calls us with something like "/tmp/.gnome_thumbnail.0WOIDU",
  #   and on unrecognized extension we produce BMP format.
  #   Seems that it's handled Ok, but I should probably switch to PNG anyway.
  # - %s is what everyone uses, but will this handle filenames with spaces?
