V2.2.1 (elalish#589)

* added notes about twistDegree and nDivisions

* update version

* removed perf comparison figure

it is pretty outdated considering we don't have the GPU backend anymore
and performance is different now.

 [OpenSCAD](https://openscad.org/), [IFCjs](https://ifcjs.github.io/info/), [Grid.Space](https://grid.space/), and [OCADml](https://github.com/OCADml/OManifold) have all integrated our Manifold geometry kernel! Why? Because its reliability is guaranteed and it's 1,000 times faster than other libraries. See our [usage](https://github.com/elalish/manifold/discussions/340) and [performance](https://github.com/elalish/manifold/discussions/383) discussions for all the latest and to add your own projects & analyses.
 
-For example, here is a log-log plot of Manifold's performance vs. earlier OpenSCAD geometry backends:

 If you like OpenSCAD / JSCAD, you might also like ManifoldCAD - our own solid modelling web app. Our WASM is not multithreaded yet, but it's still quite fast and a good way to test out our Manifold library.

 [Manifold](https://github.com/elalish/manifold) is a geometry library dedicated to creating and operating on manifold triangle meshes. A [manifold mesh](https://github.com/elalish/manifold/wiki/Manifold-Library#manifoldness) is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc. Further information can be found on the [wiki](https://github.com/elalish/manifold/wiki/Manifold-Library).
 
-This is a modern C++ library that Github's CI verifies builds and runs on a variety of platforms. Additionally, we build bindings for JavaScript ([manifold-3d](https://www.npmjs.com/package/manifold-3d) on npm), Python, and C to make this library more portable and easy to use.
