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.
