It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request introduces several optimizations to CanvasPath to reduce data copying, aligning with the ongoing SkPathBuilder API migration. The changes primarily involve leveraging a cached SkPath via the path() method to avoid redundant snapshots in operations like addPath and op. Additionally, the shift and transform methods have been refactored to perform more efficient in-place modifications on a copied SkPathBuilder, rather than creating intermediate path objects. These changes improve performance and also fix a minor bug by removing an incorrect resetVolatility() call. The implementation is clean and consistent.
