      Add static_path_tessellation macrobenchmark (#131837) · 1c7e2afc
      Matej Knopp authored
      This adds a macrobenchmark representative of a real world application that uses SVG icons. The scenario of rasterizing complex paths that don't change over time does not seem to be covered by any other macrobenchmark and shows a significantly slower impeller performance compared to skia.
      
      It's actually bit problematic to measure this because on A15 the CPU load with impeller is high enough to trigger CPU frequency change. So in order to get consistent reading I had to add a spinning background thread that would keep the CPU at highest frequency.
      
      ```objc
        [NSThread detachNewThreadWithBlock:^{
          while (true) {
            pthread_yield_np();
          }
        }];
      ```
      
      ```bash
      flutter drive --profile --local-engine=ios_profile -t test_driver/run_app.dart --driver test_driver/path_tessellation_static_perf_test.dart
      ```

      License update (#45373) · 449f4a66
      Ian Hickson authored
      * Update project.pbxproj files to say Flutter rather than Chromium
      
      Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
      
      * Update the copyright notice checker to require a standard notice on all files
      
      * Update copyrights on Dart files. (This was a mechanical commit.)
      
      * Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
      
      Some were already marked "The Flutter Authors", not clear why. Their
      dates have been normalized. Some were missing the blank line after the
      license. Some were randomly different in trivial ways for no apparent
      reason (e.g. missing the trailing period).
      
      * Clean up the copyrights in non-Dart files. (Manual edits.)
      
      Also, make sure templates don't have copyrights.
      
      * Fix some more ORGANIZATIONNAMEs
