This seems like a good case where you want to be using wgpu (https://github.com/gfx-rs/wgpu-native https://github.com/gfx-rs/wgpu-native) rather than raw webgl

This seems like a good case where you want to be using wgpu (https://github.com/gfx-rs/wgpu-native https://github.com/gfx-rs/wgpu-native) rather than raw webgl so that you can easily upgrade people to webgpu in the browser and Vulkan on desktop in order to render with less overhead. Looks good otherwise though.
