Limit seamless rotation to TRANSFORM_INVERSE_DISPLAY children. am: aab09158 am: 87850707

                // seamlessly rotated child windows to have the TRANSFORM_TO_DISPLAY_INVERSE

                // flag. Due to limitations in the client API, there is no way for

                // 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

                // users, windows without children, and native code. This is unfortunate but

                // having the camera work is our primary goal.
