Reimplement some explicitly required methods to speed up shapes

#explicitRequirement is really slow in the case were a method is implemented already in the superclass and this slow down a lot some visualizations. I propose to explicitly define the super call to get a huge speed up on shapes (This allows to save a lot of times in the Moose visualizations)
