Programming Notes
=================
For details on how to setup a full-screen DirectDraw app, see the FullScreenMode
sample.
If the display device supports DDCAPS2_CANRENDERWINDOWED then to make GDI write to
a DirectDraw surface, call IDirectDraw::FlipToGDISurface, then create a clipper object
which GDI uses when drawing. To display a dialog, then simply create and show it
as normal.
If the display device does not support DDCAPS2_CANRENDERWINDOWED (some secondary
graphics cards are like this) then the card does not support FlipToGDISurface.
So it is necessary instead to have GDI make a bitmap of the dialog to be drawn,
then blt this bitmap to the back buffer. However, this sample does not show how to
do this technique,
