NAME
       al_backup_dirty_bitmap - Allegro 5 API

SYNOPSIS
              #include <allegro5/allegro.h>

              void al_backup_dirty_bitmap(ALLEGRO_BITMAP *bitmap)

DESCRIPTION
       On some platforms, notably Windows Direct3D and Android, textures may
       be lost at any time for events such as display resize or switching out
       of the app.  On those platforms, bitmaps created without the
       ALLEGRO_NO_PRESERVE_TEXTURE flag automatically get backed up to system
       memory every time al_flip_display is called.

       This function gives you more control over when your bitmaps get backed
       up.  By calling this function after modifying a bitmap, you can make
       sure the bitmap is backed up right away instead of during the next
       flip.
