                // the client to set this flag in a race free fashion. If we seamlessly rotate

                // a window which does not have this flag, but then gains it, we will get

                // an incorrect visual result (rotated viewfinder). This means if we want to

                // support seamlessly rotating windows which could gain this flag, we can't

                // rotate windows without it. This limits seamless rotation in N to camera framework
