Is this going to work for polar axes? I would also double-check that this doesn't utterly bork for axes3d (not that I'd expect it to work great there, just to not crash or something).

polar axes don't have ticks -- but it does appear that this needs to be updated so it's aware of when the ticks are present or not.

It doesn't seem to crash for axes3d, though as you say, it doesn't really do the right thin other than add a bit more space.

bit of a bike shed, better to do this with a dictionary?

should this be max(self.majorTicks[0].get_tick_padding(), self.minorTicks[0].get_tick_padding())) ?

Never underestimate pathological users....

That's a good point.

Another point: are we always guaranteed at least one tick?
