gserialized_get_gbox_p()

int gserialized_get_gbox_p	(	const GSERIALIZED *	g,
		GBOX *	gbox
	)

Read the box from the GSERIALIZED or calculate it if necessary.

Pull a GBOX from the header of a GSERIALIZED, if one is available.

Return #LWFAILURE if box cannot be calculated (NULL or EMPTY input).

If it is not, calculate it from the geometry. If that doesn't work (null or empty) return LW_FAILURE.
