Concave - The top slope is 2 times the steepness entered while the bottom slope is 0%
	Convex - The top slope is 0% while the bottom slope is 2 times the steepness entered.
	S-Shape - The top and bottom slopes are 0% while the midpoint has a slope of 2 times the steepness entered.
	Uniform - The slope steepness is constant over the slope length.
