Sets the orientation of this camera. This will
be equivalent to setting each of the axes:
<code><br>
cam.setLeft(rotation.getRotationColumn(0));<br>
cam.setUp(rotation.getRotationColumn(1));<br>
cam.setDirection(rotation.getRotationColumn(2));<br>
</code>

@param rotation the rotation of this camera
