 * 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
 *
 * This should be autogenerated as well, really...
 *
 * 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...

/*
  Include generated cdecl wrappers for stdcall WGL functions

  function address must  found using wglGetProcAddress(),
  but also stdcall so still need wrappers...

  Include generated
