- rethink the setBox method. The box is now considered as an origin for transformations (see _setState). we now need a method able to handle a real setting of of the box attribute mixed with the current setBox, that could do something equivalent to:

zonard._setState()
zonard.setBox()
zonard._state.bBox = zonard.el.getBoundingClientRect()
zonard.assignCursor()
