This is a known issue, and I hope to resolve it soon...

Thanks for reporting though; if you notice any other problems, please
let me know!

The 3d plotting is great, thanks for updating it!

Another small bug: the plot_surface routine reveals bits that should be
hidden behind foreground surfaces. You can see this in the test_surface()
plot in demo.py
