Test povray isosurface using scikit-image
We now have tests of pov which is great. Thanks @dollodart.
There are some significant chunks which are still untested though.
If I install scikit-image on the main docker, will someone be able to add a small test of the isosurface rendering with pov? (@mjwaters?)
Is it possible to test a larger part of the pov code? Maybe @dollodart has some tests from the recent cleanup which could be a good starting point.
