       matrix_to_quat - Constructs a quaternion from a rotation matrix.
       Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       void matrix_to_quat(const MATRIX_f *m, QUAT *q);

DESCRIPTION
       Constructs a quaternion from a rotation matrix. Translation is
       discarded during the conversion. Use get_align_matrix_f() if the matrix
       is not orthonormalized, because strange things may happen otherwise.
