#to_sass ⇒ ::Sass::Script::Tree::Funcall

TODO:

built-in functions should be converted by the mapping if there is no equivalent, a custom conversion should be implemented. If the Hash does not contain the function, most probably, it’s a CSS built-in function and it should be copied as it is.

Note:

In its current version it could output unrecognizable functions by the Sass compiler and/or interpreter.
