Detailed Description
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.
