  Use ComPtr references for D3D objects.
  
  This is an work-in-progress CL to prototype using ComPtr.
  
  It also has a new design for internal errors that doesn't use
  FormatString, preferring a stream-based approach.
  
  One thing to be aware of is that the address operator does not
  behave as expected with ComPtr - we should use ::AddressOf.
