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   ]
