  Add a NativeWindowD3D abstract class to handle native window interactions.
  
  The previous NativeWindow class included D3D11 headers while being included in
  all D3D backds and had platform-dependent includes and members.  This
  turns it into an abstract class that only implements the minimal
  functionality for each renderer.
