Set this matrix to a rotation matrix which rotates the given radians about a given axis.
<p>
The axis described by the <code>axis</code> vector needs to be a unit vector.
<p>
When used with a right-handed coordinate system, the produced rotation will rotate a vector
counter-clockwise around the rotation axis, when viewing along the negative axis direction towards the origin.
When used with a left-handed coordinate system, the rotation is clockwise.
@param angle
the angle in radians
@param axis
the axis to rotate about
@return this
