    gdksurface-win32.c: Fix window menu positioning
    
    We ought to get the coordinates of where the window menu should be
    displayed using gdk_win32_surface_get_root_coords(), instead of rounding
    the position that we obtained with gdk_event_get_position().
    
    Also rename items a bit in the same function, and call
    gdk_event_get_event_type() for consistency with the other backends.
    
    Fixes issue #3704.
    
    
    (cherry picked from commit e941e2be7ded88728f41cdd03acd3381e45562b0)
