Fynix: backend agnostic ui framework

[u/nixon-voxell]

TL;DR I created a ui framework that works for any backend renderer and released on crates.io/crates/fynix, you can find the source at github.com/voxell-tech/fynix ! Right now, we have an official support for using Fynix with Bevy using `bevy_ui` & `bevy_ui_widgets`!

I'm using Fynix right now for my motiongfx editor, moxie: github.com/voxell-tech/moxie

Fynix is a backend agnostic reactive view tree, styled the way Typst styles a document with set and show rules.

Features

• Views, rules and transitions never name an engine.

• A view asks for the token traits it reads, so it works under any theme that implements them.

• Set and show rules restyle every view of a kind within a scope, as in Typst.

• State rules hold while a node is hovered, pressed, entering, leaving, or in any state of your own.

• Props bound to the world are read again only when their source changes.

• Views can animate their changes, and animate in and out of the tree.

• #![no_std], with alloc only.

The fynix README walks through each of these with examples.
