servo: Merge #12878 - stylo: Support clip-path (from Manishearth:clip-path); r=heycam
Todo: - [x] `set_clip_path` (probably needs a bunch of gecko bindings for running constructors/destructors) - [ ] Ensure that I've ordered the coordinates correctly - [ ] Check that it works - [x] Might want to convert NS_STYLE_FILL_RULE and NS_RADIUS to enum classes Depends on: - https://github.com/servo/rust-bindgen/pull/29 - https://github.com/Manishearth/gecko-dev/compare/servo:stylo...Manishearth:clip-path Source-Repo: https://github.com/servo/servo Source-Revision: 609d47b44fdd31b712100839e1d4c5db15dbafcd
