3D library now available for pyxel
*This is **not** a bug report!*

Just a quick note to tell you that I've ported @josefnpat [3D library for PICO-8](https://github.com/josefnpat/picocam) to Pyxel.

**pycocam** is now available at https://github.com/marespiaut/pycocam under the public domain.

Best regards!
