X11Drv: move WGL extension code

Interesting, because I can well imagine people testing for the presence of an extension by trying
to get a pointer to it.

And this is even more interesting :-)! So you have now run WoW in OpenGL mode using Wine CVS +
your patch. I'm guessing the login screen didn't look like this though (Wine 0.9.20, XOrg 7.1):

The Direct3D version is far prettier on my machine, although it does crash when I quit:

Dare I ask what your OpenGL WoW login screen looked like before you applied your patch to Wine,
please? And which version of XFree / XOrg / DRI / graphics driver you have?

Thanks,
Chris
