--- Comment #19 from Gabriel Ivăncescu  ---
Just some extra info: set_window_pos ends up calling the driver's
WindowPosChanged, which is needed at the very least (commenting it out in a
copy-pasted function breaks it again) to update it; and of course all the
necessary work before that to retrieve the valid rects and so on.

I was worried about messages sent but set_window_pos doesn't seem to send any,
since it's an internal helper, so that shouldn't be a problem either.

So I'm guessing that the patch is correct, without overcomplicating
matters—Zhiyi, please let me know if it doesn't break Office, so I can send it.
