Title:
  Screen.pixelDensity is incorrect on all devices

Status in Canonical System Image:
  Fix Committed
Status in qtubuntu:

Bug description:
  I’m testing the Screen.pixelDensity attached property
  (http://doc.qt.io/qt-5/qml-qtquick-window-screen.html#pixelDensity-
  attached-prop) in a QML app on various devices (krillin, arale, flo),
  and the screen always reports the same incorrect value: 3.93701 px/mm.

  I had a quick look at how this is implemented in QtQuick, and it calls
  into QScreen::physicalDotsPerInch(), which itself calls into
  QPlatformScreen::physicalSize(), which doesn’t appear to be
  reimplemented in QtUbuntu (UbuntuScreen).

  For reference, I want to use that property to calculate the physical
  size of the screen, as a heuristic to determine the most suitable form
  factor.
