// DXEngine.h 
// 
// DXEngine is quite a big class I use as a base class for DirectX projects. 
// It includes a lot of functionality that is made available to child classes. 
// This is a cut-down version for the tutorial. The full version also  
// includes DirectInput, DirectMusic, DirectSound and a number of DirectDraw  
// drawing utilities. 
// 
// This isn't exactly the paragon of OO design, but it works. :-)
