Oops.  Crud.  I remember *intending* to test under X11 before submitting, but clearly didn't.  Sorry.

The issue behind this error raises questions as to whether this extension is worthwhile.  It was designed for the case where the DC had been released.  What's happened here is the window has been destroyed.

I can detect that case in a somewhat hacky manner and then make wglMakeContextCurrentWINE() fail.  But the existing functions would have failed in that case, already.  So, while the extension lets us restore the context in some additional cases, it's not clear that it helps in enough to be worthwhile.

Furthermore, this extension was originally inspired by <https://bugs.winehq.org/show_bug.cgi?id=28869> but that was actually a different issue and was fixed another way.
