-- Natools.S_Expressions.Templates.Generic_Discrete_Render provides a       --
-- S-expression template renderer for discrete types.                       --
-- The template is a list of atoms, representing images in the order of the --
-- formal discrete type, optionally followed by a list whose atoms are      --
-- concatenated to form a fallback image for all others values. When        --
-- fallback image is not provided, formal Default_Image function is used.   --
