title: Having a transparent CCScene
body: <p>I am designing a game with a pause button. When the player pushes it, I am pushing a CCScene using [[CCDirector sharedDirector] pushScene:[PausePage scene]];
  My PausePageScene doesn't fill the entire screen and I would like to see the CCScene below the Pause Page. Is there a way to do that ? Because the rest of the screen is filled with black instead of being transparent
  Thanks</p>
