Doom Fire in Zig

A version of the Doom Fire effect, inspired by the excellent article by Fabien Sanglard

Notes

• SDL2 seems fairly straightforward to use via C interop.
• This is the first time I've played with Zig, there's some stuff in there that probably isn't best practice.
• Linux - you should be fine if you have a development version of SDL2 installed.
• Windows - I was using the MinGW version of SDL2 (see build.zig)
  • Headers in "deps/include"
  • Libs in "deps/lib"
• Enjoy!
