+Programming Notes
+=================
+  The basic tasks to author a simple windowed DirectDraw application are as follows:
+  
+  Initialize DirectDraw: 
+    1. Register a window class and create a window.   
+    2. Call DirectDrawCreateEx to create a DirectDraw object
+    3. Call SetCooperativeLevel to set the DirectDraw cooperative level 
+       to normal.
+    4. Call CreateSurface to obtain a pointer to the primary surface.  In windowed mode,
+       the primary surface is also the desktop window.  So the pixel format for the 
+       primary surface is based on the user's selection of display resolution. 
+    5. Create a back-buffer.  In windowed mode, this is should be an off-screen 
+       plain buffer. The back buffer is typically the same size as the window's 
+       client rect, but could be created with any size.  
+    6. Test to see if the display mode is in palettized color (8-bit or less).  
+       If it is then a palette needs to be created. This sample displays a single 
+       bitmap so it can read the bitmap palette info to read and create a DirectDraw 
+       palette.  After a palette is created, call SetPalette to set the palette for 
+       the primary surface. 
+    7. Call CreateClipper and SetClipper to create a clipper object, and attach it
+       to the primary surface.  This will keep DirectDraw from blting on top of 
+       any windows which happen to overlap.      
+    8. Create an off-screen plain DirectDraw surface, and load media content into it.  
+       For example, this sample calls DDUtil_CreateSurfaceFromBitmap() to do just 
+       this. 
+
+  When the app is idle, and it is not hidden or minimized then render the 
+  next frame by:
+    1. If movement or animation is involved in the app, then calculate how much 
+       time has passed since the last time the frame was displayed.
+    2. Move or animate the app state based on how much time has passed.
+    3. Draw the current state into the off-screen plain backbuffer.
+    4. Call Blt to blt the contents of the off-screen plain backbuffer into 
+       the primary surface.
+  
+  If the display resolution changes or an exclusive mode DirectDraw app is run, then 
+  the DirectDraw surface may be lost (resulting in a DirectDraw call returning 
+  DDERR_SURFACELOST), then handle it by:
+    1. Call RestoreAllSurfaces to have DirectDraw restore all the surfaces.  
+    2. Restoring a surface doesn't reload any content that existed in the surface 
+       prior to it being lost. So you must now redraw the graphics the surfaces 
+       once held.  For example, this sample handles this by calling 
+       DDUtil_ReDrawBitmapOnDDS()
+
+  In windowed mode, handle the following windows messages:
+    1. WM_PAINT: This is sent when all or a part of the window is needs to be 
+       redrawn.  The app may not be active at the time this is called, so if this 
+       is not handled then the window will appear blank.  To avoid this, make a 
+       call to draw the next frame here.
+    2. WM_QUERYNEWPALETTE: This is sent when in a 8-bit desktop and the another 
+       window set a new palette, but now this window has control so it needs to reset
+       its palette.  The easy way to make this happen in DirectDraw is just to call
+       SetPalette.  This will force DirectDraw to realize the DirectDrawPalette 
+       attached to it. 
+    3. WM_MOVE: This is sent when the window is moving.  Record the new window position
+       here since the blt to the primary surface needs to know the window position.
+
