NAME
       al_set_new_bitmap_depth - Allegro 5 API
SYNOPSIS
              #include <allegro5/allegro.h>
              void al_set_new_bitmap_depth(int depth)
              SETTER(new_bitmap_depth, depth)
DESCRIPTION
       Sets  the  depthbuffer  depth used by newly created bitmaps (on the current thread) if they are used with
       al_set_target_bitmap(3alleg5).  0 means no depth-buffer will be created when  drawing  into  the  bitmap,
       which is the default.
