<!-- Please describe your changes on the following line: --> This is the final PR to get basic paint worklet support. It adds support for paint worklet properties (https://drafts.css-houdini.org/css-paint-api/#paint-definition-input-properties). When a paint worklet is registered, it specifies a list of CSS properties, and is provided with their computed values when it is invoked. This is a dependent PR: * "Implemented paint worklets invoking worklet scripts" is #17239. * "Implemented paint worklets rendering contexts" is #17326. There should be tests added for this, hopefully the existing wpt houdini tests. --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #16839 - [x] There are tests for these changes <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Source-Repo: https://github.com/servo/servo Source-Revision: bc44246fc682d9f2362eaca6bba07b45c293eb42
