Pylab/twinx() and Matplotlib API inconsistency

Hello NG, I am having a couple of problems with Matplotlib

Hi Andrea,

this is indeed a bug. When we wrote support for the axis offsets, we
forgot about the use case where you might be using right ticks.

Darren, do you think this would be reasonably easy to support?
