// A scoped move-only object which is associated with a request to make a
// non-root window individually capturable by a FrameSinkVideoCapturer. This
// request is tracked as long as this object lives. Once all requests are
// destroyed, the window will no longer be uniquely identifiable by a
// viz::SubtreeCaptureId, and can no longer be individually capturable by the
// FrameSinkVideoCapturer.
// Note that making a window capturable forces the layer tree root at its layer
// to be promoted to a render surface that draw into a render pass.
// See https://crbug.com/1143930 for more details.
