The problem is that GLX doesn't get a chance, since the only place GLX
knows whether the drawable is window or pixmap is in the server, and
DRI2 protocol bypasses GLX to do this.

So I'm not really sure how we can block that.

GLX does handle it correctly for the indirect case.

I suspect we want this + a DRI2 extension to disable it for other
non-GLX use cases maybe.
