Subject: 	* (ZnCompute...Gradient): Test whether the shape has multiple 
 contours to skip clockwise contours in computing the gradient 	bbox. This
 enable the description of a filled clockwise mono 	contour.         *
 (ZnRenderTile): Slightly changed to enable drawing patterns 	using the same
 routine depending on the image status (photo or 	bitmap).
