Synthesis

A 16-glider synthesis was found by Jeremy Tan on March 19, 2019,[2] which was later improved to 12 gliders by Goldtiger997.[3]

gollark: I could make some kind of callback-based thing, but æ.
gollark: The current version uses a bunch of `defer`s to deallocate stuff as needed (I don't *think* it has any horrible memory leaks!). This works fine given that that stuff is all within one function, but I need similar logic in another one.
gollark: I just want to know how to idiomatically make GCable wrappers for the various C objects.
gollark: No, I have that stuff done.
gollark: I want a *different* set of "OPERATIONS ON RELEVANT NODE THING" and no HTML generation at the end, and it would be bees to just copy-paste the function here.
