Log:
[Win32k|User32]
- Fix Get/SetWindowPlacement and everything related. Which exposed the scroll bar over
write issue, it's not refreshing the client window when it is maximized. Next thing to
fix.
- Fix ShowWindowAsync, now restore and minimize all works. This is based on wine but in
reality it's based on Windows queuing event messages used in server side internal
calls. Also this patch includes the server side hooking points.
- Removed one ugly API.
- Fixes bug 6239, 6739 and client window restore from maximize and the incremental
crawling down issue when parent window is minimized then restored.
