Canvas: Repaint on devicePixelRatio Change
Handle moving between high- and normal-DPI displays.
The texture gets a setCanvasWindow() call on screen
change. Read window->effectiveDevicePixelRatio() here
and set m_canvasWindowChanged on change to trigger
a repaint if there was a change.
Task-number: QTBUG-37095
