This runs wgsl shaders and rust shaders and compares the output. If the output differs, the test fails. Differential testing is better than snapshot testing or golden file testing as there are no reference files to get outdated. Note that we are only using wgpu for now, but I want to also vary the host-side crate / use `ash`. At least we are using `wgpu`'s vulkan support on linux, so we are not just testing naga's translation.
Without this it waits on the package lock anyway
Looks like this option isn't there anymore?

I think I'd like eyes on this before I do a clean up in case people have major feedback. |
