drawText is having issues in a release build. Skottie sometimes asserts in debug mode. This possibly has something to do with memory alignment - like https://skia-review.googlesource.com/c/skia/+/155980 helped fix. Patchset 9 shows off integrating Skia drawing to an HTML canvas using Ganesh. To see it locally, set up https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html and then set $EMSDK to be that directory. Then run make clean make local-example and navigate to http://localhost:8000/skia-wasm/example.html Patchset 20 shows off Skottie animating directly to a Canvas.
