bool bsta_int_histogram_2d::find_edge	(	unsigned int	peak_y,
		unsigned int	peak_x,
		float	newslope,
		float	edgepct,
		unsigned int &	edge_x,
		unsigned int &	edge_y,
		bool	front
	)

Find where peak drops to X% along normal on either front or rear edge of diagonal slope.

Here the "front" is the top edge, "rear" is the bottom edge
