Seth Hillbrand 25f8b1ce72 pcbnew: Update multiple zone segments 
Where we can get away with lower segment counts (localizing an anchor),
we keep the low-def 16 segment count.  Intermediate values and values
that are visible to the user are set to high definition.  Most are
simply hints to the inflation correction but where they show, the user
show see smooth lines.
