We have a semantic issue with the blockages layers. Two meanings are possibles:
1. They represent an exact area where no metal should be put, and that area has been computed by the standard cell abstractor and *do not* need to be expanded. This is the forbidden area, period! 2. They match the shapes of the components inside the standard cell (say an horizontal segment). In that case, the blockage *must be expanded* by the minimal spacing rules as any fixed wiring already present. It is not clear to me what is the accepted norm. This commit stays on semantic [1]. The semantic is implemented in PowerRailsPlanes::Rail::doLayout().
