Demonstrates some flexibility available with SwapChainPanel in Windows 8.1

It does so by changing MiniCubeXaml-Sample. For rendering the Window-Background is not used any-more, a custom UserControl is used. MainPage equps it with TextBlock in front, back and even as content. Panel is rotated and scaled. Scaling makes the rendering blurry, in further Samples/Versions it might be interesting to compensate it.
