Many things work, some don't. Notably, genPOI doesn't work, and there's some signedness comparison stuff going on in the C extension. This also completely drops support for Python 2, as maintaining a C extension for both Python 2 and 3 is a pain and not worth it for the 9 months that Python 2 is still going to be supported upstream. The documentation needs to be adjusted as well. All of the few tests we have pass, and rendering a map works, both with a configuration file and without. We can also use optimizeimages. Concerns #1528.
