Latest Chrome Canary (111.0) removed support for deprecated WebGPU support for SpirV shaders, and those need to be specified in WGSL format.
For this we now use the Tint compiler (it is the compiler for Dawn: https://dawn.googlesource.com/tint, and it has an executable that can consume SPIR-V and emit WGSL).
The WASM build of Tint was obtained here:

Current WebGPU shader transpiling:
This breaks support for directional shadows (shader which passes the shadow map to a function no longer compiles) which will be investigated separately.
