  Update script to install ANGLE binaries in installed Chromium
  
  Useful when debugging a WebGL test, the script that installs ANGLE
  binaries in Chrome Canary on Windows is updated to also allow installing
  ANGLE binaries in Chrome Dev on Linux.  On Linux, the script needs to
  run as root.
  
  Bug: angleproject:6507

  # update_chrome_angle.py:
  #   Helper script that copies ANGLE libraries into the Chromium Canary (on Windows) or Dev (on
  #   Linux) installed directory. Testing ANGLE this way is much faster than compiling Chromium from
  #   source. The script checks for the most recent build in a set of search paths, and copies that
  #   into:
  #
  #    - /opt/google/chrome-unstable on Linux
  #    - the most recent Canary installation folder on Windows.
  #
  # Only works on Linux and Windows.
