I did some testing on this and tried to send some messages to the
window from inside the WM_DISPLAYCHANGE message handler. I did not
manage to get any message through, not even WM_DISPLAYCHANGE.
HWND_BROADCAST doesn't help either. Broadcast messages are sent to
other windows (e.g. the device window) as expected.

It is possible that WM_DISPLAYCHANGE and WM_IME_NOTIFY are generated
by d3d9 rather than just whitelisted.

The behavior is also different if the device is created by a thread
that does not own the window. In this case the owning thread has to
pump messages, otherwise CreateDevice gets stuck. A lot more messages
can be seen, but not WM_WINDOWPOSCHANGING / WM_WINDOWPOSCHANGED.

I don't plan to spend more time on the filtering behavior until we
find an application that has trouble with the current code though.
