Not quite right, Dave. The Windows display driver interface supports direct rendering to the video hardware. It is certainly possible for an application to do graphics operations into a memory buffer which is latter copied onto the screen, but it is just as easy to do the operations on the screen directly (so that no copying is necessary).
