The inverted painting, the rubber band replay and the changed() receiver lived in DiagramView, which the unit tests cannot link, so the update-flag regression was only covered through a stand-in view. They now live in PaletteGraphicsView, a QGraphicsView subclass with no other dependency, and DiagramView derives from it. The view tells a subclass through paintingInverted(bool) when it renders for an inverted display; DiagramView forwards that to the diagram. The grid dot rule moves out of Diagram::drawBackground into QET::Palette::gridDotColor(). tst_qetpalette now links the real class: gridDotColorSoftensInvertedDots, paletteViewFollowsThePalette (light sheet, dark sheet at text contrast with a red box still red and the paintingInverted calls in order, back to light), paletteViewKeepsSceneUpdatesFlowing (three whole-scene updates and a selection each repaint, scene set after construction), paletteViewDrawsTheRubberBand.
