Remove usage of getUsedAxes(), after the refactor of setupGrid, it's

no longer needed, and possibly misleading - hopefully, nobody else has
used it yet; also refactor getAxes() and remove annoying
backwards-compatibility stuff in it, it probably didn't help anything
and prevents one from using getAxes() in the obvious way
