If wines WGL implementation is fully implemented then it may be a good idea switching to wgl, a
wgl implemenatation would also make debugging much easier because wined3d can be run under windows
to isolate problems.

Nick Burns also started work on a wgl version of wined3d that I haven't got around to fully
merging yet, I can send you the patch.
