Jeff Patterson 3e34a6d55f Fill the dark canvas buffer and keep one scene connection
QGraphicsView::render() paints only what the scene draws, so a scene
without a background brush left the off-screen buffer uninitialized
and the inversion turned that memory into noise. The buffer is now
filled white first, which the inversion turns into the Base color.

listenToScene() connected a new receiver on every setScene() call and
never dropped the previous scene's. It now keeps a single connection
and replaces it.
