+     *   1. Hardware composer's capability to composite contents with the

+     *   2. Hardware composer's ability to composite contents when sRGB contents
+     *      and the chosen data space contents coexist;
+     *   3. For better blending, consider using pixel format where the alpha
+     *      channel has as many bits as the RGB color channel.
+     *
+     * @return dataSpace is the default data space that SurfaceFlinger expects.
+     *         The data space must not be Dataspace::UNKNOWN, if unspecified,
