NAME
       get_x_rotate_matrix, get_x_rotate_matrix_f - Construct X axis rotation
       matrices. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void get_x_rotate_matrix(MATRIX *m, fixed r);

       void get_x_rotate_matrix_f(MATRIX_f *m, float r);

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