WineD3D can't create a device without a Window. For DirectDraw and D3D7 running without a Window is valid, at least to a certain extent. The D3D light test does so, and some games use this for some purposes. So I need to do something for the case HWND == 0 or the d3d surface is not a primary surface.
Why not use the 'desktop' window to do it ? No idea what window will be used to display when not in Desktop mode (maybe the X root window ?).
This seems to be a good idea. Is this WND_DESKTOP or can I get it with GetDesktopWindow?
