This class represents an Affine object that rotates coordinates around an anchor point. This operation is equivalent to translating the coordinates so that the anchor point is at the origin (S1), then rotating them about the new origin (S2), and finally translating so that the intermediate origin is restored to the coordinates of the original anchor point (S3).

The matrix representing the rotation transformation around an axis (x,y,z) by an angle t is as follows: 

             [   cos(t)   -sin(t)   0   x-x*cos(t)+y*sin(t)   ]
             [   sin(t)    cos(t)   0   y-x*sin(t)-y*cos(t)   ]
             [     0         0      1           z             ]

For example, to rotate a text 30 degrees around the Z-axis at anchor point of (50,30): 

Text text = new Text("This is a test");
text.setX(10);
text.setY(50);
text.setFont(new Font(20));

text.getTransforms().add(new Rotate(30, 50, 30));

private Class Rotate.MatrixCache

extends Object
Class Inheritance
Matrix cache. Computing single transformation matrix elements for a general rotation is quite expensive. Also each of those partial computations need some common operations to be made (compute sin and cos, normalize axis). Therefore with the direct element computations if all the getters for the elements are called to get the matrix, the result is slow. If a matrix element is asked for, we can reasonably anticipate that some other elements will be asked for as well. So when any element needs to be computed, we compute the entire matrix, cache it, and use the stored values until the transform changes.
