Adapted for Luanti

For best memory performance: have luaJIT & it's FFI library (this should be built into luaJIT), and add LEEF-Math to your trusted list (so it can require() call the FFI library).

Various useful bits of game math. 3D line intersections, ray casting, 2d/3d vectors, 4x4 matrices, quaternions, etc.

This is a fork of CPML (for LÖVE/love3d), it's been ported over the minetest so it can be used in whatever you need it for. Documentation can be found here: https://minetest-unified-library.github.io/LEEF-Math/.

For possible future contributors: documentation must be generated manually when a commit is made, because I haven't set up workflows (and have no idea how to).

TODO:

Vec3s and Vec2s are not currently adapted for functionality with MT vectors, fix.
