I compiled this project with RUSTFLAGS=\"-C target-feature=+simd128,+bulk-memory,+nontrapping-fptoint,+relaxed-simd -C opt-level=3\" wasm-pack build --target web --out-name index --out-dir wasm/dist --release --mode no-install and got a pretty impressive result.

Any chance this could be merged and released?

@khiemtong Thanks for your interest in resvg-js.

In the long run, this feature will definitely be released. However, given that this increases the size of the wasm file, a separate npm package may need to be released. These tweaks would require some work, which I don't have time for at the moment.

While the package size would increase - the compiler should be able to strip out the dependencies (wasm files) that are not required, right? (I'm using it in an Angular App and the wasm file is not compiled into the bundle anyways as I'm serving it separately). However the performance gains by using SIMD are enormous. I'm seeing a 2x/3x speedup for my use-case.
