Set this matrix to a rotation matrix which rotates the given radians.
<p>
The resulting matrix can be multiplied against another transformation
matrix to obtain an additional rotation.
<p>
In order to apply the rotation transformation to an existing transformation,
use {@link #rotate(double) rotate()} instead.
