When the coordinate thorns initialise the coordinates, the have the same
parameter settings for all convergence levels. They need to adjust the
grid spacing. E.g., CartGrid3D has a convergence factor of 2 hardcoded
at the moment.
Other routines might want to perform a convergence test. For that they
need the convergence factor.
