    gdksurface-win32.c: Fix Aerosnap computation
    
    Don't get the default display when we compute the Aerosnap region, but instead
    get it from the underlying GdkSurface that we are using for the computation.
    
    Also, don't unref the monitors that we obtain from the display in the wrong
    place, which was why we had crashes whenever we triggered AeroSnap code (and we
    are actually not supposed to do that as they are owned by the GdkDisplay that
    is owned by the GdkSurface we are using), and this will eliminate lots of
    criticals that are spewed as a result.
