*
* \brief When a QNoDraw node is present in a FrameGraph branch, this
* prevents the renderer from rendering any primitive.
*
* QNoDraw should be used when the FrameGraph needs to set up some render
* states or clear some buffers without requiring any mesh to be drawn. It has
* the same effect as having a Qt3DRender::QRenderPassFilter that matches none of
* available Qt3DRender::QRenderPass instances of the scene without the overhead cost
* of actually performing the filtering.
*
* \since 5.5
