The function glutCreateWindow returns a value.
The Ada mapping, then, will also return this
value, as programmers might want to keep it.
  If you do not need the return value, the
program must still follow Ada rules which state
that all parameters of a subprograms must be
handled, be they in, in out, out or return.
