+Programming Notes
+=================
+  For details on how to setup a windowed mode DirectDraw app, see the WindowedMode
+  sample. 
+  
+  To use overlays in general do the following steps in addition to those needed to 
+  author a windowed mode DirectDraw app:
+    1. Check to see if hardware supports overlays - check IDirectDraw::GetCaps 
+       for DDCAPS_OVERLAY.
+    2. Size the window to meet the hardware overlay size restrictions.
+    3. Create an overlay surface (create it with 1 backbuffer if needed), and 
+       set its pixel format to a desired format that is supported by the device.  
+    4. Set the dest color key on the overlay to the background color of the window. 
+       Be sure to choose a color for the background of the window that Windows typically
+       does not use otherwise, the overlay will be drawn on top of overlapping windows.
+    5. Call UpdateOverlay to display or hide the overlay on the desktop.  WM_PAINT is 
+       a good place for this.
+    6. When WM_SIZE or WM_MOVE is sent, then update the src and dest rects and 
+       check to make sure that they are within the hardware limits.
+       
+  To animate the overlay, instead of drawing to the off-screen plain back buffer as 
+  in windowed mode case, just draw to the the overlay's backbuffer then flip it.
