Concerns issue #1486.
Inner/outer corners apparently have their data from ancil data instead
of Minecraft's stuff, so we might need to fix that in the future.
I've had to fight rst a lot to get this right, somehow the code
block after the last bullet point breaks if you explicitly number
the enumerated list instead of using auto-enumeration. Like legit,
change `#.` to `12.` and it'll break. No clue why.
I've adjusted the macOS instructions slightly to be more general,
e.g. do not advise symlinking a specific Python executable of a
specific version, just tell people they should make sure it's in
their environment.
And yes, on Windows, python.exe is whatever version you have installed,
so if you install Python 3, python.exe is going to be Python 3.
I've removed the FreeBSD instructions because they only talk about
working around ports potentially using Python 2.6, which is no longer
relevant. If somebody here uses FreeBSD and has anything to add to the
instructions not already covered by the Linux instructions, let me know.
Python 3.7 requires using the xenial images in Travis-CI. It appears
that they do not yet have newer distro version images available, so
that's the best we can get for now.
There's some stuff left to do, like properly do the functools.partial
stuff, and check that the uuidcache is actually working. But hey,
player markers work at least, and so does --skip-scan.
Still needs a port to argparse though.
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.
