#include <allegro.h>

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


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.
