Fix issues on HiDPI displays
This patch fixes widgets rendering on HiDPI displays and notifies
about the a potential device pixel ratio change when the window is
moved. This addresses the blurriness when a web view is moved
between an attached LoDPI screen and HiDPI screen resulting from
the device pixel ratio not being updated.
