Alright, to clear this up.

WinG is simply an effective way to draw bitmaps off-screen, then blast
them to the current frame buffer very quickly.

However, this is still not fast enough in most cases.  DirectDraw
replaces this.  DirectDraw is a comprehensive graphics API, which
allows buffering, writing direct to the screen, and hardware support-
so your 2D card can help with moving bitmaps, a huge advantage.

3D DDI however, is simply another Win95 graphics component that
provides a very "thin" software layer that 3D game designers can
"hook" into and provide support for any 3D accelerator card that has a
3D DDI driver.  It is seperate from DirectDraw, and WinG.
