NAME
get_scaling_matrix, get_scaling_matrix_f - Constructs a scaling matrix. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void get_scaling_matrix(MATRIX *m, fixed x, fixed y, fixed z);
void get_scaling_matrix_f(MATRIX_f *m, float x, float y, float z);
DESCRIPTION
Constructs a scaling matrix, storing it in m. When applied to the point (px, py, pz), this matrix will produce the point (px*x, py*y, pz*z). In other words, it stretches or shrinks things.
