Support Warning

WebGPU is currently only supported on Chrome starting with version 113, and only on desktop. If they don't work on your configuration, you can check the WebGL2 examples here.

//! Shows how to render a polygonal [`Mesh`], generated from a [`Rectangle`] primitive, in a 2D scene.
//! Adds a texture and colored vertices, giving per-vertex tinting.
