NAME

       create_zbuffer - Creates a Z-buffer for a bitmap. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       ZBUFFER *create_zbuffer(BITMAP *bmp);

DESCRIPTION

       Creates  a  Z-buffer  using the size of the BITMAP you are planning to draw on. Several Z-
       buffers can be defined but only one can be used  at  the  same  time,  so  you  must  call
       set_zbuffer() to make this Z-buffer active.

RETURN VALUE

       Returns  the pointer to the ZBUFFER or NULL if there was an error. Remember to destroy the
       ZBUFFER once you are done with it, to avoid having memory leaks.
