Correct rounding of GCell horizontal size in GCell::doGrid(). 

* Change: In Anabatic::GCell::doGrid(), the GCell where square using the
    slice height as side. This was leading to vertical edges with slightly
    different capacities when the vertical picth was not a multiple of
    the horizontal one. This was not a bug per se as the global router
    is able to manage any interval.
      Now the horizontal side is rounded on the slice step.
