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
       front must not be equal). A front vector of 0,0,-1 and up vector of 0,1,0
       will return the identity matrix.
