            Colors might be defined in the material ( QskGradientMaterial,
            QSGFlatColorMaterial ) or attached to each point ( QSGVertexColorMaterial ).

            The main advantage of using colored points is, that the material becomes
            independent of the coloring and the scene graph is able to batch the nodes
            ( https://doc.qt.io/qt-6/qtquick-visualcanvas-scenegraph.html ).

            However adding the color information for each point increases the memory
            footprint.

            The default setting is to use colored points where possible. Note, that
            this is what is also done in the Qt/Quick code.
