[roll] Roll fuchsia [flatland] Modify how `root_transforms` are computed for hit testing. The original motivation was noticing that the `root_transforms` in GlobalTopologyData are only used in view tree computation, not rendering. So we can improve RenderCPU metrics (and overall CPU use, since most frames don't modify the view tree) by deferring this computation until needed. An additional improvement is to use a vector instead of a map. The `root_transforms` are only used during hit testing, which is already based on indices into the global topology vector. Since these indices are already available, it's faster to index into a flat vector.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
