** registration [#sf-reg]
 giflib/util/gifovly.c inspired me.
 gifovly.c is based begore GIF89 spec,
 no transparent, no animation.
 
 I think so good extend gifovlay.c
 to include GIF89a function,
 , mofidy overlay to overlap routine, 
 and provide php extension make us happy.
 
 ex)
  new $go = new GIFOverlap();
  $go->add(get_file_contents('background.gif'));
  $go->add(get_file_contents('avatar.gif'));
  $go->add(get_file_contents('item.gif'));
  echo $go->output(); // item.gif overlap avatar.gif overlap background.gif

My poor english, But I beleave heartful communication.
