/** Geometric primitives in \imp behave a bit differently than most values.

    Most classes in \imp are initialized to a defined state (sometimes a null
    state) by their default constructor. For efficiency reasons, certain ones,
    mostly low-level geometric types, are not. They act like built in types
    in C++ in that they only have a defined state if set (or initialized).

    In addition, they are not comparable, or hashable.

    See the \ref geometricprimitives :Geometric Primitives" entry for more
    information.
