public class Morphing2D extends Object implements Shape
A morphing shape is a shape which geometry is constructed from two other shapes: a start shape and an end shape.
The morphing property of a morphing shape defines the amount of transformation applied to the start shape to turn it into the end shape.
Both shapes must have the same winding rule.

public Morphing2D(Shape startShape, Shape endShape)
Creates a new morphing shape. A morphing shape can be used to turn one shape into another one. The transformation can be controlled by the morph property.

public double getMorphing()
Returns the morphing value between the two shapes.
setMorphing(double)
public void setMorphing(double morph)
Sets the morphing value between the two shapes. This value controls the transformation from the start shape to the end shape. A value of 0.0 is the start shape. A value of 1.0 is the end shape. A value of 0.5 is a new shape, morphed half way from the start shape to the end shape.
The specified value should be between 0.0 and 1.0. If not, the value is clamped in the appropriate range.
