Set this matrix to the rotation - and possibly scaling - transformation of the given {@link Quaterniond}.
<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.
<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(Quaterniond) rotate()} instead.
