Return the next point on the CurvilinearShape (one step beyond current point) and adjust from top-left to center coordinates for the object traversing the curve based on its width and height.
Return the next point on the CurvilinearShape (one step beyond current point) and adjust from top-left to center coordinates for the object traversing the curve based on its width and height. Return null if past end point. This is an optional method.

Set (or reset) the location for the Arrow as a line.
Set (or reset) the location for the Arrow as a line. The bend parameter is ignored for this class, since arrows are straight.

Set (or reset) the location for a line/curve using an explicitly given control point.
Set (or reset) the location for a line/curve using an explicitly given control point. This is an optional method.
The Arrow class uses Java's Path2D class to create a line with an arrowhead on the far end. The main line is defined by points p1 and p2. Points p3 and p4 are the corners of the triangular arrowhead.
