Multiple meshes or different colored vertex sets on a single QQuickItem?

[qttester5]

Is it possible to have more than one draw call for a QQuickItem subclass? It seems to only support one QSGGeometry instance, which suggests it cannot. For example, suppose I am drawing a multi-colored chart in QQuickItem's updatePaintNode, how would I do this if it only supports one set of vertices?

The QSGNode that you create in updatePaintNode() may have as many children (with their own geometries) as you'd like.
