NAME
       get_align_matrix - Rotates a matrix to align it along specified coordinate vectors. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void get_align_matrix(MATRIX *m, fixed xfront, yfront, zfront, fixed xup, fixed yup, fixed zup);

DESCRIPTION
       Rotates a matrix so that it is aligned along the specified coordinate vectors (they need not be normalized or perpendicular, but the up and
