bool SG_Shape_Get_Dissolve	(	CSG_Shape *	pShape,
		CSG_Shape *	pSolution
	)

Assuming supplied shape object is of type polygon and has several parts, it is important that the point order of outer rings (i.e. not lakes) is clockwise, that of lakes counter-clockwise to be processed correctly by the Clipper dissolve function. This is in accordance with the simple features definition but in contrast to ESRI's Shapefile format.
