[roll] Roll fuchsia [flatland] Fix rotation and order operations for 3D matrices. Currently, matrices are operated in the wrong order. Translation would be the first order of operations, and then scale. For instance, this would mean that the translation amount would be scaled giving an incorrect value. Secondly, since the 2x2 submatrix rotated by 90/270 takes the following form: 0 -sin(angle) sin(angle) 0 We, therefore, cannot scale using only the diagonal elements. This fixes both issues.

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 via the IRC channel #fuchsia on Freenode.
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.
