these messages are caused by giving libart_lgpl a set of points for a
shape that either:

	1) have multiple instances of the same x-coordinate values
	2) if they wrap around to form a closed polygon (or even
	    "start" to do so to form a non-closed polygon), they
	    do not wrap counter-clockwise (IIRC)
