There was a problem hiding this comment.
Somehow evidently I screwed this up again relative to ProcessingProjection.

Partially addresses #26.
Adds a new
processing_wasmcrate that operates similar toprocessing_ffi, i.e. wrap in a WASM/JS compat function.We're helped by running in a single thread on desktop already, but on web we can't ever block the main thread, so we need a few additional non-blocking flavors of some methods that currently block on desktop.
We're generating JS bindings here because it's helpful to test. Most implementers will likely just bind directly to the WASM module.
Adds a
justfileto help coordinate some of this. If you're not familiar,justis a common task running in the Rust ecosystem that's like a simplified make.
