SceneGraph 2D API (QPainter) WebKit, Qt Components and QML will create content nodes for the scene graph and the scenegraph will compose / render all content through and OpenGL surface provided by the Lighthouse layer. OpenGL Enabled WindowSurface Raster Engine GL Engine 2D API's will primarily serve as a content feeder into the scenegraph, typically layers that need to be composed.
