[Bug 43711] XReparentWindow __wine_x11_whole_window

https://bugs.winehq.org/show_bug.cgi?id=43711

--- Comment #4 from Stan  ---
Seeing as how I can't use XEMBED, I want to use straight out reparenting  with
the Wine window GetPropA(hWnd, "__wine_x11_whole_window") but then the
reparented child thinks it's at 0, 0 and the parent window might be at 252, 29
or whatever.

How do I get the parent and child to sync when I've only got a Windows message
event loop to work with ie DefWindowProc

I've tried sending a ConfigureNotify event to the Wine child window using the
parent's x y coords and it doesn't do anything.
