## Detailed Description

Controls layers Drawn in a frame graph branch.

A Qt3DRender::QLayerFilter can be used to instruct the renderer as to which layer(s) to draw in that branch of the frame graph. The Qt3DRender::QLayerFilter selects which entities to draw based on the Qt3DRender::QLayer instances added to the QLayerFilter and as components to the Qt3DCore::QEntity.
