A couple flaws - the menubar doesn't draw at all (when WS_EX_NOREDIRECTIONBITMAP is set). Also resizing is not smooth.
Use Present(0) and DwmFlush logic to resize more smoothly.
Performance is pretty bad with integrated adapter on my hardware, so always choose discrete.
Make the present strategy a settable parameter, for experimentation.
Use DXGI flip in the normal case, hwnd for resize.
Some of the functions needed for flip mode are unavailable in Windows 7, so load them optionally.

This is an attempt to address #17, merging the flip + hwnd hybrid approach discussed in #19 (and thanks to the testers).
The hybrid approach only works on Windows 8.1 and up, so we use optional functions to set up composition and the swap chain. On Windows 7, all presentation is with the hwnd approach.
