This is not true on modern Windows. If we know when we're in
fullscreen we can get in a special fullscreen mode that gets extra
perfomance by disabling the Desktop Window Manager. We could write
directly into the buffer that will be sent to the display (using a
flip operation), saving a copy at every frame (on the other hand we
need to handle the resizing ourselves).
