Okay, I'm submit a patch for wgl headers then. I should be able to just move
the relevant declarations from dlls/opengl32/wgl.h to include/wingdi.h without
any problems I think. Please let me know if there are any gotchas I should
watch out for.

Well I am only working on removing glX calls from wined3d and replacing them
with wgl calls so I'd rather not impact the GL code if possible. At first I
didn't quite understand your question, so let me see if I got this right.
Currently wined3d directly links to libGL.so (via EXTRALIBS in the Makefile).
So if I wanted to use opengl32.dll (for wgl), and I added it to IMPORTS it would
override the libGL.so calls?
Currently that is what I am doing, but if that is causing all GL calls to go
through opengl32.dll then that is not good... Since there are not too many wgl
calls, it would probably be best to GetProcAddress them. In fact, I am doing
this for a few wgl extensions anyways, so I might as well just do it for all of
wgl. I'm not that familiar with the wine linking issues, so please let me know
if I am off here.
