* Include generated cdecl wrappers for stdcall WGL functions
*
* There are extensions to the wgl*() API as well; again we call
* these functions by using wglGetProcAddress() to get a pointer
* to the function, and wrapping it for cdecl/stdcall conversion
*
* We arrange to resolve the functions up front, as they need a
* context to work, as we like to use them to be able to select
* a context. Again, this assumption fails badly on multimontor
* systems...
