Programming Notes
=================
For details on how to setup a full-screen DirectDraw app, see the FullScreenMode
sample.
One simple method to animate sprites in DirectDraw is author a single bitmap
file to contain many frames of animation. The program then stores the current frame
indicator in each sprite's state. From this current frame indicator, it can
progmatically derive a src rect that encompasses only a single frame
of animation in the off-screen plain surface. The rect then is blited from the
off-screen plain surface to the back buffer.
InitDirectDraw() in the sample shows how to build an cached array of these source rects.
DisplayFrame() then access this array based on each sprite's current frame.
