<!-- Please describe your changes on the following line: --> Implemented drawing a CSS style value into a canvas, which is needed for the Houdini CSS Paint API. This PR is dependent on #17364. --- <!-- 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 #17432. - [X] These changes do not require tests because the existing CSS paint API wpt test cases test this behaviour. <!-- 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: 76ad913870cec3f01731d324967ed191fd5c6be3 --HG-- extra : subtree_source : https%3A//hg.mozilla.org/projects/converted-servo-linear extra : subtree_revision : 9cbcb16f1b30c5fb25c0dc7d291c6c78638fcc5f
