    <thetext>[Coordinated Graphics][GTK][WPE] Implement DrawingAreaCoordinatedGraphics::shouldUseTiledBackingForFrameView

DrawingAreaCoordinatedGraphics doesn&apos;t implement shouldUseTiledBackingForFrameView
DrawingArea::shouldUseTiledBackingForFrameView always returns false.

RenderLayerCompositor::rootLayerConfigurationChanged() doesn&apos;t work as expected.
