Public bug reported:

Qt 5.6 supersedes QT_DEVICE_PIXEL_RATIO with three variables:
- QT_SCALE_FACTOR, which works the same way.
- QTSCREEN_SCALE_FACTORS, which lists values per monitor.
- QT_AUTO_SCREEN_SCALE_FACTOR, which automatically picks a value for each monitor.

Documentation needs to take these new variables into account and we need
to start using the new variables where applicable (the old one still
works, but triggers warnings with Qt 5.6).

Note: tests/unit/units have failures with Qt 5.6.

** Affects: ubuntu-ui-toolkit (Ubuntu)
