Well, this is the big question. I think we should ask Alexandre what happens
in the Wine build system if a symbol is exported both by a Win32 DLL (here
OpenGL32.DLL) and a Linux ELF DLL (here libGL.so) and a Wine DLL requires to
be linked to both.
In my opinion I would have both GLX and WGL code co-exist... I really fear
that to make some game happy in WGL, we would 'cheat' and report some stuff
which is not exactly aligned with what the GPU really supports. Which means
that WineD3D will not be able to trust what WGL reports as it may be tweaked.
Finally, if we get some 'GLX-only' extensions (maybe threading related - one
can always hope :-) ), how could one support that using WGL ? Add our own
fake extensions to WGL and 'thunk them' ?
