Polish MapViewer example

This patch does some improvements to the MapViewer example.
Namely:

- sliders, which have been problematic in many ways, are now from
QtQuickControls 2, and this solves a couple of glitches.

- changing map provider now retains tilt, bearing and field of view,
if possible.

- High DPI scaling is enabled by default in main()

- the slider panel is open at start
