GraphicsWindowWin32 only exists under Windows, and given that make current is so rarely called and calling it twice with the same value won't break anything I'd suggest we just integrate your hack without any extra checks. As I mentioned before the extra checks could well introduce bugs of their own so I'd be very cautious of doing it when the actual gain will be negligible in terms of performance. So I'd suggest merge your change as is. I was hoping for a bit more feedback from other Windows users before merging though...
