    `Cloneable`, `EventTarget`

      public class Scale
      extends Transform

  This class represents an `Affine` object that scales coordinates by the specified factors. The matrix representing the scaling transformation around a pivot point `(pivotX, pivotY, pivotZ)` with scaling factors `x`, `y` and `z` is as follows:

                    [   x   0   0   (1-x)*pivotX   ]
                    [   0   y   0   (1-y)*pivotY   ]
                    [   0   0   z   (1-z)*pivotZ   ]

  Since:

                                        throws NonInvertibleTransformException

      Description copied from class: `Transform`
      Transforms the relative magnitude vector by the inverse of this transform. The vector is transformed without applying the translation components of the affine transformation matrix. This method can be used only for a 2D transform.
      Overrides:
        `inverseDeltaTransform` in class `Transform`
      Parameters:
        `x` - vector magnitude in the direction of the X axis
        `y` - vector magnitude in the direction of the Y axis
      Returns:
        the inversely transformed relative magnitude vector represented by a `Point2D` instance
      Throws:
        `NonInvertibleTransformException` - if this transform cannot be inverted

    - #### inverseDeltaTransform

          public Point3D inverseDeltaTransform​(double x,
                                               double y,
                                               double z)
                                        throws NonInvertibleTransformException

        `z` - vector magnitude in the direction of the Z axis
      Returns:
        the inversely transformed relative magnitude vector represented by a `Point3D` instance
      Throws:
        `NonInvertibleTransformException` - if this transform cannot be inverted

    - #### toString

          public String toString()

      Returns a string representation of this `Scale` object.
      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of this `Scale` object.
