auto range limits for spines: please kick the tires

if you update from svn and play around with the demo, especially by
panning and zooming in the figures, you'll get an idea of what I've

Neat! One small thing: in Figure 2 (the four subplots with differently
placed spines) if I zoom and pan subplot 4, I can make its spines appear
in subplots 2 and 3. Curiously enough, they don't show up in subplot 1.
