    public class Shear
    extends Transform
    This class represents an Affine object that shears coordinates by the specified multipliers. The matrix representing the shearing transformation around a pivot point (pivotX, pivotY) with multiplication factors x and y is as follows:
                  [   1   x   0   -x*pivotY   ]
                  [   y   1   0   -y*pivotX   ]
                  [   0   0   1       0       ]
     

    For example:

    
     Text text = new Text("Using Shear for pseudo-italic font");
     text.setX(20);
     text.setY(50);
     text.setFont(new Font(20));
    
     text.getTransforms().add(new Shear(-0.35, 0));
