I don't want to stop supporting Windows 10.  I'm referring specifically to Windows 10 RTM, the very first version of 10, which has fallen entirely out of Microsoft's support system. If we only need to support versions of Windows that Microsoft is supporting that would be Windows 10 2016 (1607) in which case there's no need to mess with all the DLL and function pointer retrieval in this code. You can just issue direct calls to SetThreadDpiAwarenessContext and friends.

I will add that though we might say in this thread that we don't need to worry about Windows 8 or earlier I really and truly could not find any public statement to that effect anywhere.
