      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

      Add convex path and non-AA paint to shader warm-up (#28614) · f776cc19
      liyuqian authored
      One of our important client's SKP shows that this could improve one of
      their janky frame by 20ms. This also improves our
      flutter_gallery__transition_perf's worst frame time by ~20ms.
      
      On the other hand, 15ms has been added to the start-up latency. I guess
      it's a little faster to compile the shader on the start-up because we're
      compiling a lot of shaders there and the CPU cache must be hot.

      Shader warm up (#27660) · a44f174e
      liyuqian authored
      This patch adds a default shader warm up process which moves shader compilation from the animation time to the startup time. This also provides an extension for `runApp` so developers can customize the warm up process.
      
      This should reduce our worst_frame_rasterizer_time_millis from ~100ms to ~20-30ms for both flutter_gallery and complex_layout benchmarks. Besides, this should also have a significant improvement on 90th and 99th percentile time (50%-100% speedup in some cases, but I haven't tested them thoroughly; I'll let our device lab collect the data afterwards).
      
      The tradeoff the is the startup time (time to first frame). Our `flutter run --profile --trace-startup` seems to be a little noisy and I see about 100ms-200ms increase in that measurement for complex_layout and flutter_gallery. Note that this only happens on the first run after install or data wipe. Later the Skia persistent cache will remove the overhead.
      
      This also adds a cubic_bezier benchmark to test the custom shader warm up process.
      
      This should fix https://github.com/flutter/flutter/issues/813 (either by `defaultShaderWarmUp`, or a `customShaderWarmUp`).
