Feel free to use or distribute it, part or whole, for any non-commercial
use, preferably crediting me. 

This uses a complex DirectDraw surface - primary and back buffers - to
display a black rectangle moving across a white screen, together with frame
rate information. 

It is merely a demonstration program, and whilst it should work, it is
merely a toy and makes no pretence at being optimised, efficient, highly
practical or clever. 

It uses exclusive mode, makes no attempt to check for later DirectX
interfaces, doesn't try to restore lost surfaces, etc., etc.... 

But it will get you up and running, showing how to create DirectDraw
objects, how to call their methods, and how to perform a primitive
animation... 

I've kept away from macros, and have left some routines rather long so you
can easily see what's happening. Hopefully the comments are detailed
enough. 

The two include files contain all that's needed ...
