    Window class intended to be used as a simple, generic Window.

    to position 0.0f, 0.0f with a size of 1.0f x 1.0f.

    /note
    The C++ name of this class has been retained for backward compatibility reasons.  The intended usage of
    this window type has now been extended beyond that of a gui-sheet or root window.
