RFont is a lightweight single-header font rending library that's built onto of stb_truetype.
The library was made because I used to use Fontstash.h until I looked through the file and realized how bloated and unoptimized it is.

It supports multiple rendering backends and allows you to easily create your own backend.

I made this single-header window abstraction library; it’s similar to glfw in terms of what it can be used for. It’s also designed to be lightweight and attempts to offer better performance. Check out the repo if you’re interested and star it if you like it. https://github.com/ColleagueRiley/RGFW
