NAME
       quat_mul - Multiplies two quaternions. Allegro game programming library.


SYNOPSIS
       #include <allegro.h>

       void quat_mul(const QUAT *p, const QUAT *q, QUAT *out);


DESCRIPTION
       Multiplies two quaternions, storing the result in out. The resulting quaternion will have the same effect
       as the combination of p and q, ie.  when applied to a point, (point * out) =  ((point  *  p)  *  q).  Any
       number  of  rotations  can  be  concatenated  in  this  way.  Note  that quaternion multiplication is not
       commutative, ie. quat_mul(p, q) != quat_mul(q, p).
