    win32: Fix placement at initial position
    
    Positioning windows at 0,0 post creation failed, because it
    was mapped with CW_USEDFAULT, but private->x/y still said 0,
    so moving it to 0,0 did nothing. We now always position the
    window at the right place, even when not mapped, but we
    create it at CW_USEDEFAULT initially and store that position
    before moving it to the right place.
    
    This fixes the window sizing test in testgtk and the inital
    position for the gimp toolbar.
