It turns out that Skia is much slower at drawing paint inside a clipped path than directly drawing that path. (Average frame time of 22ms vs 18ms in flutter_galary transition test.)

@Hixie do you mean updating golden images? I'm hesitant to update them and merge this now because I think @nataliesampsell is also updating the golden images and I can't pass the golden tests using her newest golden files. I'm waiting for her changes to land in flutter/flutter so I can update my golden images on top of hers. Otherwise, I'll have to keep doing flutter/goldens@111e6e9 |

I mean whatever it takes to make sure we don't regress this. :-) |

Thanks for the comment! The flutter_galary transition benchmark in our dashboard should catch the performance regression and clip.PhysicalModel.xxx.png golden images should guard the correctness. I'll check for better micro-benchmark to monitor the performance regression later. |
