NAME
       apply_quat  - Multiplies a point by a quaternion. Allegro game program‐
       ming library.

SYNOPSIS
       #include <allegro.h>

       void apply_quat(const QUAT *q, float x, y, z, *xout, *yout, *zout);

DESCRIPTION
       Multiplies the point (x, y, z) by the quaternion q, storing the	result
       in   (*xout,   *yout,   *zout).	 This  is  quite  a  bit  slower  than
       apply_matrix_f(), so only use it to translate a few points. If you have
       many  points,  it  is  much more efficient to call quat_to_matrix() and
       then use apply_matrix_f().
