// Contains the base Direct3D application class which provides the 
// framework interface for the sample applications.  Clients are to derive  
// from D3DApp, override the framework methods, and instantiate only a single 
// instance of the derived D3DApp class.  At the same time, the client should 
// set the global application  pointer (gd3dApp) to point to the one and only 
// instance, e.g., gd3dApp = new HelloD3DApp(hInstance);
