Simple patch to illustrate scene graph port

This is a simple patch (500 loc) that is work in progress that illustrates the porting path to the scene graph, initially based on the FBO based painted item.

It requires QML_NO_THREADED_RENDERER=1: paint() is otherwise called from the rendering thread, which will start a timer that was constructed in the gui thread. That's not possible. I think the NO_THREADED_RENDERER workaround is fine since we anyway want to move away from PaintedItem and position the tiles in the scene
graph ourselves. If the node updates can only be done from the rendering thread, then we need to find another solution for the timer problem...
