bevy_fast_light: Simple 2D lighting for Bevy focused on performance over features

[leomeinel]

I have been working on a crate that provides simple 2D lighting for Bevy focused on performance over features.

The crate is still in the early stages of development and this post is more meant to showcase my early progress than an actually usable crate.

The codebase is quite small so if you are interested in how I did this, please take a look. I'm not sure if I will add any other types of lights since that might bloat up the codebase, but I'm very happy if I get feedback or suggestions :)

I also want to thank all bevy contributors for their awesome work and for making this possible. 🥇

Limitations

• PointLight2d does not look nice with low ambient light.
