Looks like we've been stuck on Emscripten fastcomp backend, misssing out on all new optimisations between LLVM 6 and LLVM 11 and going via slow asm.js pipeline when building.
This changes Docker images for Emscripten projects to point to emscripten-upstream instead and commits the updated artifacts.
This was a no-op in Wasm anyway. Now that I've added ability to control logging upstream, let's use it to disable it from compiled unit altogether for a slight win in size and perf.
This makes building simpler and allows us to potentially use multithreading version in the future.
For now points to a custom fork of OxiPNG that enables WebAssembly support, as PR is still pending review.
Benefits:
- newer versions of the libraries
- zlib: 1.2.8 -> 1.2.11
- libpng: 1.6.18beta04 -> 1.6.34
- much fewer dependencies to install (as libs are already in optipng archive and we don't need napa)
- much smaller build thanks to customised versions of zlib and libpng containing only APIs necessary for optipng itself: 238950 -> 177359 bytes
- much faster build thanks to preconfigured libpng and stripped APIs: 2m15s -> 40s
- much simpler build script: 77 -> 46 lines
This delegates loading of Wasm modules to Webpack itself, making wrapper code simpler.
Emscripten-generated modules are still using custom loading glue as they're not compatible with Webpack.
Nightly is no longer necessary for wee_alloc, so we don't need to rely on unstable versions of Rust anymore.
As a bonus, this reduces size of each Rust-related Docker image by >1 GB:
- `squoosh-rotate`: 2.94GB -> 1.87GB
- `squoosh-resize`: 3.09GB -> 2.02GB
- `squoosh-hqx`: 3.13GB -> 2.06GB
