Inochi2D - Realtime 2D Animation written in D

[Luna]

Hey folks, I have for the (almost) past 2 years been working on a 
real-time 2D animation library called 
[Inochi2D](https://github.com/Inochi2D/inochi2d) and tooling for 
it. Recently I went full time on the project due to generous 
donations on GitHub Sponsors and Patreon.

The library and tooling is mostly implemented in D, with the only 
exception being SDL2, OpenGL and Dear Imgui being used in the 
tooling for the UI.

The project allows you to create and rig segmented 2D art (akin 
to Live2D inc.'s Cubism product) for animation. Allowing you to 
animate the model in real-time either using face tracking [eg. 
with the Inochi Session 
tool](https://github.com/Inochi2D/inochi-session) or more 
traditional animation methods. This kind of tooling is often used 
in games as well as for 
[VTubing](https://en.wikipedia.org/wiki/VTuber), a kind of 
entertainment art form where people use real-time 2D animated 
puppets as their avatars for livestreaming.

I'm planning to release an update for [Inochi 
Creator](https://github.com/Inochi2D/inochi-creator), the tool 
used to rig and animate Inochi2D puppets, on October 10th.
