I am unable to build due to a ShaderC dependency. I tried various avenues to fix it to no avail. Fedora 36

I updated the code to wgpu version 0.22 thus I do not need shaderc anymore. I spotted strange behavior in the projections and I am unable to run the web version although it compiles with wasm-pack build --target web.
