[PATCH v4 0/3] MR9036: wined3d: Conditionally update saved window state in fullscreen mode.

[Matteo Bruni (＠Mystral)]

For Assassin's Creed Syndicate. When switching from fullscreen to a smaller windowed resolution, it calls `SetWindowPos()` centering the window, then calls `ResizeTarget()` and finally `SetFullscreenState()`, and expects the window to preserve the position.

Window style handling is a bit iffy because of the manipulation we do when entering fullscreen, but that's not really new.
