I'm generating spriv of glam master branch versus glam refactor branch and overriding what glam rust-gpu is using via a .cargo/config overrive.

This is with Vec3 being repr(simd) on master.

I'm compiling using cargo run --bin example-runner-wgpu.

File sizes when built with master:

cam@zx:~/Projects/rust-gpu (main)$ ls -lah target/spirv-builder/spirv-unknown-unknown/release/*.spv
