Prefetch img, scripts and stylesheets during parsing <!-- Please describe your changes on the following line: --> Eagerly tokenize html input, and scan for `script` and `img` tags which can be prefetched into the cache. This allows resources to be loaded concurrently, which would otherwise be loaded sequentially due to being blocked by script execution. On the cloth webgl demo, this takes the time-to-paint down from 732ms to 560ms. --- <!-- 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 #3847 - [x] These changes do not require tests because it's a perf improvement <!-- 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. --> <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/24148) <!-- Reviewable:end --> |
