Programming Notes
=================
For details on how to setup a full-screen DirectDraw app, see the FullScreenMode
sample.
To animate the palette on a palettized DirectDraw surface, call
IDirectDrawPalette::GetEntries to retrieve the palette colors. Then every
frame (or as often as desired) alter this array as needed, then set the new palette
by first calling IDirectDraw::WaitForVerticalBlank( DDWAITVB_BLOCKBEGIN, NULL )
to synchronize the palette change to a vertical blank, then
call IDirectDrawPalette::SetEntries.
