I am wondering does libgdiplus from mono support offscreen rendering without requiring directdraw functions? If yes, I think I have a hint on what I must do.
The goal: begin a process of importing all of mono's code base into wine's, then contributing back the the mono project, this should result it wine having not only a better GDI+ implementation but also a working and stable .net framework too, I might think about an open source clone of Directx for x11 that uses ReactOS (Open Source NT Implementation meant to be binary compatible with Windows NT 5.2 that does not use any Microsoft code and also one of wine's primary contributors next to Codeweavers) Directx headers and hooking into both the XRender and GLX extensions, but that depends on what happens next.
