DESCRIPTION

17       Constructs a quaternion that represents a rotation between from and to.
18       The argument t can be anything between 0 and  1  and  represents  where
19       between  from  and to the result will be. 0 returns from, 1 returns to,
20       and 0.5 will return a rotation exactly in between. The result is copied
21       to  out.  This  function  will create the short rotation (less than 180
22       degrees) between from and to.
