public Matrix3f multLocal(Matrix3f mat) {
        return mult(mat, this);
    }
Multiplies by the matrix argument and returns the (modified) current
instance.

<p>Note that matrix multiplication is noncommutative, so generally
q * p != p * q.

@param mat the right factor (not null, unaffected unless it's
    {@code this})
@return the (modified) current instance
