Remarks

The standard backdrop brush samples the area immediately behind the visual where it is used. The host backdrop brush tells the compositor to sample from the area behind the visual, before the window is drawn. The host backdrop brush is translucent and it hit-tests as opaque. The app cannot read the pixel data back.
