-- (base "symbol 0" "symbol 1" "symbol 2" ...) --
-- (left-padding "symbol") --
-- (image (0 "symbol 0") (2 "symbol 2") ...) --
-- (max-width "max width" ["overflow text"]) --
-- (min-width "min width") --
-- (padding "left-symbol" "right-symbol") --
-- (padding "symbol") --
-- (right-padding "symbol") --
-- (sign "plus sign" ["minus sign"]) --
-- (width "fixed width") --
-- (width "min width" "max width" ["overflow text"]) --
-- Top-level atoms are taken as the image for the next number. --
