Graphical Functions and macros

Those macros and functions create a graphical element as soon as they are evaluated and return the Nil result, can only be used within a “User” graphical element1 .

Those can be used within macros, but these ones will be evaluated only if those macro are executed while creating a “User” graphical element.
