        * Hwnd.cs:
          - Added Reparented property to allow tracking of Window Manager
            reparenting actions (which affect X/Y calculations of toplevel
            windows)
          - Made ToString() print window handles in hex
        * XplatUIX11.cs:
          - AddConfigureNotify(): Now uses reparented state off Hwnd to
            determine if X/Y needs offsetting
          - AddConfigureNotify(): Fixed offset calculations
          - Now adds ReparentNotify messages into the queue
          - Now processes ReparentNotify messages and causes a
            WM_WINDOWPOSCHANGED message to be sent upstream if a window
            is reparented (as most likely it's X/Y coordinates are changed
            due to that)

These fixes will fix the 'random' window repositioning of toplevel windows
when setting one of the properties that affect size or location (Left, Top,
Size, Location, Bounds, etc.) Thanks to Eric Butler for a testapp that
showed this problem.
