Re-order drawing of spines and axis objects.

dopplershift · dopplershift · commit 33408fadbd2f · 2014-03-09T21:05:20.000-06:00
This gives the spine a chance to update the axis object before draw.
This is sensible given that the axis can be registered with the spine
so that it can modify it, and is necessary for some use cases.
