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.
