Examples of ae.java.awt.geom.AffineTransform.rotate()

ae.java.awt.geom.AffineTransform.rotate()
Concatenates this transform with a rotation transformation. This is equivalent to calling concatenate(R), where R is an AffineTransform represented by the following matrix:
```
 [   cos(theta)    -sin(theta)    0   ] [   sin(theta)     cos(theta)    0   ] [       0              0         1   ] 
```
Rotating by a positive angle theta rotates points on the positive X axis toward the positive Y axis. Note also the discussion of Handling 90-Degree Rotations above. @param theta the angle of rotation measured in radians @since 1.2

        at.translate(x, y);
        // now gradient point 1 is at the origin
        x = pt2.getX() - x;
        y = pt2.getY() - y;
        double len = Math.sqrt(x * x + y * y);
        at.rotate(x, y);
        // now gradient point 2 is on the positive x-axis
        at.scale(len, 1);
        // now gradient point 1 is at (0.0, 0), point 2 is at (1.0, 0)


        float p0, p1, p3;

        // transform unit circle to gradient coords; we start with the
        // unit circle (center=(0,0), focus on positive x-axis, radius=1)
        // and then transform into gradient space
        at.translate(cx, cy);
        at.rotate(fx - cx, fy - cy);
        at.scale(radius, radius);


        // invert to get mapping from device coords to unit circle
        try {
            at.invert();
