Let's have a function:
void al_clear_screen() { // or rather al_clear_bakbuffer()
  old = al_get_target_bitmap();
  al_set_target_bitmap(al_get_backbuffer());
  al_clear_target_bitmap();
  if (old != al_get_backbuffer())
    al_set_target_bitmap(old);
}

and make a promise we won't do this with every drawing function.
