If you want to build without WebAssembly, there are some comments to change at the top of WADrawer.ts, then npx webpack
I made a renderer in WebAssembly, but it's not better than rendering in JavaScript until Firefox fixes OffscreenCanvas. https://bugzilla.mozilla.org/show_bug.cgi?id=801176 So it's disabled.
build scripts use emsdk installed with these instructions: https://emscripten.org/docs/getting_started/downloads.html
drawWasm.ts is automatically generated by build script in wasm
build-dev.sh and build-prod.sh will run that before the rest of the build process
