We need to disable security because a game we are developing currently uses insecure lua features. I don't think the software rendering env variable was doing anything, but if it was, I think it was counter-productive.

do not use std::from_chars TODO squash
The motivation was to avoid some copies of the CapnProto messages. I think this is possible using ZeroMQ, but it seems much easier with CapnProto RPC. It also reduces third party deps (no ZeroMQ).
potentially faster than TCP on localhost
this seems to result in a significant performance boost (39 -> 57 FPS on devtest game on awake-oyster, which has Quadro M4000).
It's way faster than the --headless we put into Irrlicht. On a machine with: * Quadro M4000 GPU * E5-2630 v4 CPU FPS goes from ~20 to ~59 on devtest game. sleep after starting XVFB TODO squash"
it is not needed We can run headless on linux using XVFB This means we don't need to use SDL2 fix test for linux mesa TODO squash
