From what I have seen GL3 is very different. It would be like maintaining a 
GTK and a QT backend in one library. They use very different calls 
(glBegin/glEnable and so are gone), need different WGL contexts and so on.

Sure in case of a wined3d-gl3 you'll end up fixing bugs twice. But for quite a 
number of bugs you'll need to patch both gl2 and gl3 anyway.

Second what do you guys things of regressions? We really should keep 
ddraw/d3d7/d3d8/d3d9 stable. Else it will take another 3 months before it is 
in a decent shape again.

My suggestion would be to create a new wined3d with the same interface as the 
current wined3d. If needed ddraw/d3d8/d3d9 can use this wined3d too. 
Personally I would add d3d9ex.dll like on Vista which can use wined3d-gl3.
