VideoOverlay accepts a stream of QImage frames (e.g. from a tracking webcam or a recorded video) and uploads each frame to a QRhi RGBA texture sampled by a screen-aligned quad. The overlay is composited after the 3-D scene with alpha blending so it can be used as a picture-in-picture reference, an AR background, or a chroma-keyed avatar overlay.
