Chapter - Null element
[Inform requires that there always be at least one g-element in the world. We therefore provide this object, which is not associated with any canvas and is display-inactive, and so will never be shown; it can also serve as a null element if we need it.]
g-null-element is a g-element. The display status is g-inactive.
