ArrangeLayersInfo

struct ArrangeLayersInfo
{
	// matrix geometry
	int		rows;
	int		cols;

	int*	indices;
	int		count;

	// % of page width
	int		leftMargin;
	int		rightMargin;
	int		hGap;
	int		hMin;		// min layer width

	// % of page height
	int		topMargin;
	int		bottomMargin;
	int		vGap;
	int		vMin;		// min layer height

	int		nRepeat;	// repeat count of calls to improve visual, typically 3 times is good enough
	int		threshold;	// LP (positive) or 0.01% of page width/height (negative) threshold to allow arranging layers, 0 to disable

	DWORD	dwCntrl;	// ALICNTRL
};
