Calculate the anchor point position for a text label.
When the requested label placement is of INSIDE or OUTSIDE type the returned anchor point for the text label is the middle point of the outer arc for the given slice; when the requested label placement is of CENTER type the returned anchor point for the text label is the middle point of the line segment bisecting the slice. The text alignment is always centered when the requested label placement is of CENTER type else it is dependent on the value of the angle defined by the horizontal axis and the ray bisecting the slice.
