Draws the session's camera image behind everything else in a Filament scene, filling the viewport. This is what makes rendered content look placed in the real world.

ARKit delivers the camera image as a pixel buffer with a luma and a chroma plane. Each plane becomes a Metal texture that shares the buffer's memory, imported into Filament for the one frame it is drawn in; the material converts to RGB.

Creates the Filament engine to render this session with. Only an engine created here can draw the camera image through CameraBackground: on Android it uses the OpenGL backend and shares the GL context ARCore writes the image in. On iOS it is a Metal engine with nothing special about it.
