getPoint2d_p_ro()

int getPoint2d_p_ro	(	const POINTARRAY *	pa,
		int	n,
		POINT2D **	point
	)

This function can only be used on LWGEOM that is built on top of GSERIALIZED, otherwise alignment errors will ensue.

New function to read doubles directly from the double* coordinate array of an aligned lwgeom POINTARRAY (built by de-serializing a GSERIALIZED).
