get_x_rotate_quat, get_y_rotate_quat, get_z_rotate_quat - Construct axis rotation quaternions. Allegro

       Construct axis rotation quaternions, storing them in q. When applied to a point, these  quaternions  will
       rotate  it  about  the  relevant  axis  by  the specified angle (given in binary, 256 degrees to a circle
       format).
