[3dprinter-general] Bug#742704: ImplicitCad in Debian

Hey Bas,

Presently, I no longer maintain ImplicitCAD. I've been pretty poor
about handling this. I put it out temporarily to work on some other
stuff and ended up getting pulled away. Now I work full time on
machine learning research. I just don't have the cycles to keep
another project in my head anymore. :/

In any case, right now there's no upstream for ImplicitCAD. I've
spoken to a few people who were interested in taking over maintenance,
but they haven't ended up doing so.

ImplicitCAD, unfortunately, has a bunch of rough corners. Mostly,
these deal with the computational costs of rendering objects at high
resolutions and rendering issues at low resolutions.

If you're interested, I'll try and pull together remaining interest in
ImplicitCAD and see if we can find a new maintainer. It'll need to
wait until after the NIPS submission deadline, though.

All the best,
