NAME

       gui_set_screen - Changes the bitmap surface GUI routines draw to. Allegro game programming
       library.

SYNOPSIS

       #include <allegro.h>

       void gui_set_screen(BITMAP *bmp);

DESCRIPTION

       This function can be used to change the bitmap surface the GUI routines draw to. This  can
       be  useful  if you are using a double buffering or page flipping system. Passing NULL will
       cause the default surface (screen) to be used again. Example:

          BITMAP *page[2];

          /* Allocate two pages of video memory */
          page[0] = create_video_bitmap(SCREEN_W, SCREEN_H);
          page[1] = create_video_bitmap(SCREEN_W, SCREEN_H);

          /* Page flip */
          show_video_bitmap(page[0]);
          gui_set_screen(page[0]);
