Rendering effects requires actually rendering another item. The effect is defined by another item that is rendered instead of the original item. For items that have an effect we do not render the children, since the effect is only applied to the layer not the individual items. We set layer.enabled temporarily to false, this ensures the effect is not rendered as part of its parent item. To detect the effect we use the source property an check if it points to the ShaderEffectSource. If one of the children inside the effect is transformed we have to update the effect item. If layer.enabled or layer.effect is changed we set the dirty flag on the item and all children.
