Set this matrix to a rotation matrix which rotates the given radians about the origin.
<p>
The produced rotation will rotate a vector counter-clockwise around the origin.
<p>
The resulting matrix can be multiplied against another transformation
matrix to obtain an additional rotation.
<p>
In order to post-multiply a rotation transformation directly to a
matrix, use {@link #rotate(double) rotate()} instead.
