I thought of the same thing, as DDraw -> D3D7 -> WineD3D -> OpenGL is a quite 
long chain. I abadonned it as too much work at first, but it's surely worth

How about moving the current 2D code to WineD3D, and making DDraw running over 
WineD3D in any case. Then WineD3D could decide wether to use plain X11, DGA 
or OpenGL for 2D rendering. :)

Maybe we should have a close look at the details of such a thing. I do not 
really recommend a ad-hoc attemt, as d3d7->WineD3D was nearly too much.
