This is a massive breaking change for all existing users of CanvasKit. It will be (one of the only) changes in 0.19.0 to make the transition easier. Suggested reviewing order: - index.d.ts (to see type changes). Notice SkPicture still has Sk prefix, but no other types do (this felt "right" since Sk is part of the name of the type, but I can be swayed on this). - canvaskit-wasm-tests.ts - tests/*.spec.js - interface.js and helper.js - html examples - markdown files Change-Id: I3b3d3815df2078f986893df3c70101d6248c117d Docs-Preview: https://skia.org/?cl=322617 Bug: skia:10717 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/322617 Commit-Queue: Kevin Lubick <kjlubick@google.com> Reviewed-by: Nathaniel Nifong <nifong@google.com>
