Subject: [PATCH] winex11.drv: Make Update _NET_WM_STATE before replaces the
 size hints for the WM_NORMAL_HINTS property.

For windows without WS_THICKFRAME style, _NET_WM_STATE must be set first,
otherwise _NET_WM_STATE_MAXIMIZED_VERT and _NET_WM_STATE_MAXIMIZED_HORZ
cannot be removed when the window is restored to normal.
