Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How do softwares like Sketchup handle rendering?
In general, I'm a big believer in immediate mode for 3D user interface elements. Before I worked at SketchUp, I did research into designing an immediate mode GUI library for VR applications. And many 3D applications use a similarly principled library called imgui for 2D graphics within their scenes.

Capturing the WebGPU Ecosystem
https://github.com/coconut-xr/apfel-kruemel works today, I only know about battery-optimized software in the context of games though.
https://felt.com/blog/svg-to-canvas-part-2-building-interact... and https://github.com/servo/pathfinder/ might also be of interest.

Servo, the parallel browser engine written in Rust
Parts of Servo to enable the use of the GPU for compositing layers were merged into Firefox years ago.

It's a shame that Patrick Walton didn't get a chance to finish his work on the Pathfinder GPU renderer.
>Pathfinder 3 is a fast, practical, GPU-based rasterizer for fonts and vector graphics using OpenGL 3.0+, OpenGL ES 3.0+, WebGL 2, and Metal.

What do you believe Firefox is missing?
It uses too much CPU and performance leaves much to be desired compared to Chromium. They were going to use Pathfinder in Firefox to solve this problem, but since Pathfinder is discontinued due to the massive layoffs at Mozilla, the project was abandoned. And they need a replacement IMO.

Stereokit – open-source mixed reality library by Microsoft
I am not an expert in the area, just somebody who read up on it after realizing desktop in VR does not work out for me (and usually low res is not a problem).
I think something like https://github.com/servo/pathfinder (newer) and as you mentioned SDF (older) are the latest approaches.

PSA: OffscreenCanvas now enabled by default on nightly only
This is exciting! And, by the way, are you planning to implement something similar to Servo's Pathfinder in Firefox?

Getting into GUI: Shapes moving on networks
Also on my list was pathfinder. There the documented crate is vastly different from https://github.com/servo/pathfinder which looks much more promising – it comes with a few examples, some of wihch might help me get started, maybe?

I wrote a web based text editor to showcase sauron framework, but it turns out better than I expected, less than 20ms typing latency.
Don't forget gpu-based text rendering (e.g. #1, #2, #3). It's still in its infant stages, and seems to be mostly untouched over the past 5 years, but I suspect it will become the preferred method for rendering text later.
What are some alternatives?
imgui - Dear ImGui: Bloat-free Graphical User interface for C++ with minimal dependencies
Skia - Skia is a complete 2D graphic library for drawing Text, Geometries, and Images.
nanovg - Antialiased 2D vector drawing library on top of OpenGL for UI and visualizations.
lyon - 2D graphics rendering on the GPU in rust using path tessellation.
sauron - A versatile web framework and library for building client-side and server-side web applications
Servo - Servo, the embeddable, independent, memory-safe, modular, parallel web rendering engine
StereoKit - An easy-to-use XR engine for building AR and VR applications with C# and OpenXR!
