Title:
  Chromium launch script should follow ubuntu Scaling setting to work on
  HiDPI screens

Status in chromium-browser package in Ubuntu:
  Confirmed

Bug description:
  Chromium supports the --force-device-scale-factor=X.Y parameter, and
  it should be used in the chromium launch script in order to respect
  the unity scaling settings.

  So when $XDG_CURRENT_DESKTOP is Unity, chromium should read these gsettings keys:
    com.ubuntu.user-interface scale-factor
    com.canonical.Unity.Interface app-scale-factor-monitor
    com.canonical.Unity.Interface app-fallback-to-maximum-scale-factor

  And using these valuse to compute the proper X.Y scale parameter to be
  used for defining a force-device-scale-factor (if the user has not
  provided another one).

  The logic that should be implemented must match what's done in
  UnitySettings [1].
